An American Nunavut?

What do you guys think of the idea of a state "for Native Americans", kind of like Nunavut Territory in Canada is "for the Inuit"? I think it's an interesting concept because while people of today shouldn't pay for any wrongdoing that others did 150 or 200 years ago, it wouldn't be that hard; after all, Indian Reservations function as their own sovereign entities, like their own states or almost even like their own countries. It wouldn't be too much of a stretch to just make a huge slice of land, pre-existing Indian Reservation or not, and just make it a 51st State.>
