The last sprite here is actually created using existing player assets that should be released eventually™
The hairstyles on sprites 1 and 3 don't mesh well with our hat-hair mask so aren't really a possibility in their current form.
The outfits themselves may be, aside the shrine maiden, which has a slightly different body type and would need adapting.
It'd be nice if we had some sort of makeup system to support the blush etc. specifically, rather than making it the default.
