4th Harem Member Thoughts, Give Feedback?

 So as you guys know by now the main comic is basically in cryosleep as I  build my brand so strong that I can sustain it indefinitely and never  have to pause it again. Things are going well on track and I've seen a  pretty sizeable uptick in Patreon since launching the Arena content.  We're talking like +$50 in pledges so far. This will hopefully increase  as we do more and more matches with even more exciting matchups, and I  have further plans to bring in even more recurring revenue. But what I'm  asking you guys about right now isn't entirely related to that, but  it's kinda something that's been on my mind for a while now.
 

I wanted to ask though how people would feel if I revealed the 4th Harem  Member before she ever gets introduced in the story. Here me out.
 

The 4th Harem Member was originally someone else entirely. But the one  who was GOING to be #4 got shifted up to #5 like 4-5 months ago after I  had this idea to introduce someone into the story a lot sooner. If you  want to know why I changed that around, it's because it kinda dawned on  me that Futura turned out a lot less kuudere and a lot more tsundere  than she was ever planned to. Rizl was supposed to be the tsundere, but  Futura is the sassy, exasperated tsundere and Rizl is the angry one.  Characters evolve and change like that, but it does make the dynamic a  bit unbalanced. Tali was supposed to be the loving girl, Futura, the  neutral one, and Rizl was the angy gal. I set things up this way since  we were supposed to spend a couple of arcs with just the 4 of them  together before the 4th girl joined.
 

Anyway back when I decided to secretly alter my plans and add a new girl  inbetween Rizl and the PLANNED #, well, Things were incredibly  different back then, and I was planning a series of 4 Panel comics  similar to the Ask series except they'd be canon slice of life things.  The plan was to get like one of these done a day, and I had written a  good bunch of em, but as things stand now I will not ever be able to do  this series by myself anytime soon. If I can't even work on the main  comic in peace then I sure as shit don't have the power to do a daily 4  panel thing on the side.
 

The thing I'm getting at is I was planning to secretly introduce the 4th  Harem member as the introduction to this side comic, and become a  recurring character in it before she crossed over to the main one comic  in between the Goblin arc and the Moonstained Manor arc, where she would  be formally inducted. The reason it worked in my head is because,
 

1. This character is a joke. A legitimate member of the group with her  own personality and such, yes, but very much a gag character. She  wouldn't get in the way of the ongoing character narratives I have  planned for the more serious Harem members.
 

2. She would not effect the group's current power level at all really,  she would make them a tiny bit stronger but barely so. The original #4  was going to be a good deal stronger than the original members of the  Harem (who would eventually catch up to her Shounen style), but this is  balanced out because spoilers. Similar to Futura this char has a big  limiter but it's a lot less severe than Futura's. But the new #4 is very  fucking weak in most circumstances until a lot later on.
 

3. She fills a niche for a species that should probably be in the main cast but one that I had no plans for.
 

4. Importantly at the time, although she is regular sized she is able to  change sizes and would have taken up almost no panel space in big group  drawings when the harem were all in shot, and would only have to be  full size when doing things or sex. We're talking like Pikachu on Ash's  shoulder size, if a little smaller.
 

5. Obviously as you might have figured from context clues, she would  have brought balance to the early Harem and would be on the 'loves Hero  very much' side next to Tali. The original #4 is hard to explain. Like,  really hard. She also would have balanced it out, but... uh... hmm.  Spoilers. Lot of stuff going on there.
 

So I'm kinda at a weird place regarding her. I think sometimes I should  just announce her, start drawing her, involving her in art, promo stuff,  Arena, and so on, and just mention that she'll be in the main comic one  day. But also I'm torn because I feel like that'd be a slippery slope.  What's to stop me from then deciding 'well, you know, it'll be YEARS  till I reach Harem Member #5 in the main comic... since I can't even  make the fucking comic from lack of money... why don't I just do what I  did with [REDACTED] and just start drawing her now?' and so on with the  other Harem members I have planned until we reach all 7 of the currently  planned ones. Which would be hard for a few of them since one is  explicitly a twist member and I'd have to make any content regarding  them make sure it doesn't explain any reason as to why she's part of his  Harem lol...
 

The Harem model is based very much on Luffy's crew from One Piece, but  unlike Oda I don't get to rapidly draw my comic every day of my life  because I don't get paid for it. I have a vision similar in scope to the  giant epic that One Piece morphed into over the years, but I get paid  from the bonus stuff around MHFAP!, not MHFAP! itself sadly. I'm not  really paid to tell my story but to make characters and art that take  place inside my story's universe (which is why I recently resolved to  just build up my brand so big that I can work on the comic as much as I  want)- And so I have this big pile of secret characters who've been  living in my brain for like 3 fucking years that I wish I could draw.  All my other art friends have all their beloved OCs that they get to do  cute shit with and I'm just like *grumbles incoherently*.
 

And then part of me feels like if I did this for #4 I'd be leading  people on. Like oh yeah, that's [REDACTED]. She's not in the comic yet  but if you pay me more we'll get there one day! And I don't really want  to send that kind of message.
 

Instead of a poll like when I asked you guys if I should start drawing  the Artifacts, I figured I'd just let you guys comment about my thoughts  and I'll gauge the consensus for myself.
