Perhaps you could do beltless versions for the toddlers, if you still have PSDs and such from the original project? (That makes the most sense to me, especially when I consider the likely result of a toddler + chain belt). Of course, that would make it impossible to texture reference ... but you can't do much texture referencing for these kinds of clothes anyway. You have to edit out the boob shading for the kids & toddlers, and the toddlers have a different texture size anyway ...

But in other words, YES, I think this is an awesome project, and I would download it in heartbeat! Thanks, Hat!
