Oh I think Sphynx's are gorgeous! If KittyCats could do some tweaking to the face shape and maybe add a more pointed thin tail I don't see why it would be difficult to make these cats. They aren't all rail thin - some of them have cute little Buddha bellies like the Peterbald. There are also Elf cats with turned back ears and Levkoys that look like little foldies! As far as the fur is concerned, hairless cats can have a variety of colored patches on their skin so they could come in different color patterns. It's a lovely suggestion and I'd definitely want one if it happened
