We can work on avatar and game of thrones then.
For Korra, I did have an old RP that I was hoping to adapt, if you wanted to take a look:

For game of thrones, the idea was that in Westeros, the girls of noble houses aren't potty trained and kept in diapers as a form of chastity and general control. This would probably follow Arya, just because I think she'd look cute in diapers.
