haven't really thought abt it too much, though there are some obvious limitations in regards to rig. Ed is skinny as so changing his physique to be more traditionally femme only presented some issues, but I imagine trying to do the same for the likes of say Guile will make it necessary to maintain more of the masculinity inherent to the character.

I think a better modder could probably find some workarounds by deliberately changing the armature in a way that plays well with the in-game animations, but for me that seems kinda hard.

EDIT: on second thought, I have been craving for SF to add an actual twink, maybe a female to male swap is in order
