Americans needs to decide whether the issues is that the constitution is just badly written or whether the supreme court is trying to intentionally destroy democracy to help their right wing friends. Or whether both are true.
This isn't a crazy or impossible proposition, it can be done with just a law. We already form some courts in a similar way, so it's also not unprecedented. It even avoids the naked partisanship of a simple court-packing.
As far as I can tell, nobody who matters is talking about it yet. So. Hope is... remote.
It's a road map to where we end up with a similar document but a different culture.
