If Dems take back the House redistricting reform better be one of the first bills they pass. Independent commissions for every state!
I don't know if that would hold up without a SC composition change and subsequent ruling, but...they could potentially pass legislation that ensures there are independent commissions redistricting every ten years
in between the state reapportionment periods as managed by the Constitution; in other words, redistricting every 5 years via 2 different methods.
On the other hand, that might be just as vulnerable constitutionally-speaking as your idea.
