I'm sure it's not the best place to put it, and I'm also almost sure that it will be lost, but anyway...
About number 5, sex anims. We already have a huge library of animations made for Skyrim. There is absolutely no need to do new ones, there is an easy way to just retarget them all on any other humanoid skeleton. I can help with that if you give me all old animations in fbx, and old and new skeletons in their initial A or T poses. There rest is a matter of 10 minutes.
I'd really help with animations a lot, I work as an animator, but I don't want to dive too deep into modding stuff (extracting, unpacking, converting, stuff into and out of engine etc), and I don't know who to contact about it to offer help
