Hey there! I love the input! The variation in sizes is doable, although futas in MC's world are more "shemale-ish" so they've GOT to the BIG.
Regarding cosplay, I think you've already seen Alex in MC's dream with the demon "costume" on. There's some more of this on the way, not in the next update, but in the following one. I'm sure you're going to smile when you see it! Cheers ♥
