i was more talking about making this like nishys animations would change based on her overall size so if you choose a giant form then her animations would adapt to these new giant animations but if you pick her normal size then basicly the animations would adapt
a idea to help with this is having a check list where you can toggle animations or each size
im guess when you say she has her own set of stuff is because of the size diffirence but you could also adapt the member sizes to nishys size as well so if shes a giant then she uses diffirent ones
and for the rare types like the gang bang and other rare animations you could just force a toggle to trigger her normal size this could also help you make things like nishy giantess animations and many other new animations and allow you to be much more creative as you could toggle any of her sizes to make a rare animation for it
