@Vidia Unfortunatley, I found out that they aren't. I think when Disney are making a character, they have to think of the design, gameplay and popularity. I mean people keep saying about Roger Rabbit being a character would be stupid. But really, it isn't. Maid Marian is a very unlikely character to come, but if she does I'll be very happy.
Possibilities are endless. But sometimes, there is a limit.
