I really haven't watched Pocahontes (is that how you spell it?) or Mulan, but that doesn't sound racist to me. It's like those politically correct thought-police idiots who say Jar Jar was racist, the Neimoidians were racist, and Watto was racist, when in fact they're only revealing their own racism.
That said, I think the Animorphs in a Disney medium would seem more like the Power Rangers, and Cassie would, of course, be the nature princess who needs rescuing.
