There are only two broad outcomes, either things stay as they are, or much of the US is returned any remaining descendents of various treaty signatories.
The first is effectively a waste of time, the second a messy descent into hell on all sides.

Certainly messy & certainly hellish for some. For "all sides" though? I guess maybe if we're counting the fact it would paint a large target on the back of any beneficiaries.
Moving away from native title, there are also many "peppercorn leases" bequeathed to various cities about the globe - large parks carved out from once larger farming estates, now fully urbanised and embedded within a sea of million dollar lots and apartments.
Should anyone sue over the park land no longer being a pure park (for example) or for petty reasons of "peppercorn" rent not being paid (ie violation of the terms of the gift to the city), the park would be returned to the rightful descendants .. an army of (say) fourth and fifth generation offspring all at odds for recognition and weighting and a piece of very valuable real estate.
