[@Double] Nope, ALL Disney movies up until this point are Open for possible Characters =P It has to be Cannon Disney though, so No Pixar, Dreamworks or such.. So YES you can totally do a Hades Kid ^_^ Also no idea about Snow White, I had the same thought 0.o I'm a musical fan but I liked the idea of the story more then the story itself lol

also [@Burning Kitty] No you read right, Snow White doesn't have any kids ^_^ But like I said I don't count the TV Show so even if there is a child in that at some point it still counts. 

I listed the only Children from the two Movies in the first post, if they aren't there (or someone's taken them) they are fair game!
