> Restructuring the elections, congressional seat allocation, etc. would require Constitutional amendments. Unlikely to happen.

As a Brazilian, I think it's unfortunately more likely than you think. Here in Brazil, we got a completely rewritten constitution (the 1988 constitution) after our USA-backed military dictatorship ended. So if the current USA government becomes a dictatorship (which unfortunately does not seem unlikely enough right now), there's a good chance the USA will also get a brand new constitution after all that mess ends, hopefully one with better electoral mechanics.
