Finally figured out how to reposition weapons properly. It took me a few weeks, but at least now I can do it going forward. They aren't perfect in the above post, but they're much better when she's wielding them normally. I almost feel sorry for the bandit I kept resurrecting for her to shoot over and over during testing.
I still need to test Automatic Crossbow weapons. If everything goes well, I'll probably release the mod on the nexus sometime this coming week.
