More Native American characters

I loved this movie as a kid. Especially having Native American characters. I can't believe they got Graham Greene. I wish Disney would make another movie or show with Native American characters. Although this movie is really about the white kid, so I would want a Native American lead. Many of the DCOM's tend to copy old ones, so maybe it could be a similar story, except the kid is Navajo but he grew up off the reservation. They could pick a new tribe/nation even. Maybe the lead could be a girl.
