SBUI is limited to whatever animations & poses an NPC is supposed to have. I've expanded this list and added all [or close to] female animations and poses. Now there will be more options in SBUI. This does not affect any other characters.

To install: unpack to your Witcher3/Mods folder (make sure the only thing inside the folder you put into /mods is the subfolder 'content')
To uninstall: delete said folder

I've uploaded this mod since I already made it for myself and there was no point in not sharing. I'm not interested in performing this method for all NPCs in-game. Don't request it. If you'd like to create your own mods to do this to other characters, see my tutorial HERE. You'll need to know how to install/setup Wolven Kit, but won't need any experience using it.
