Unfortunately then we're back to the FPTP problem. We don't have ranked choice voting, so there can only be two parties.

If we create a new one, we'll need to convince the moderates to join, and the 35% of people who call themselves Democrat like it's a sports team. That's quite a task.

The tea party tried this approach and failed. Then they gave up and infiltrated the Republicans instead. Now they are in charge, rebranded maga.
