This is misunderstanding how political influence works. It's much harder to convince politicians to raise taxes (a core issue for Republicans) than to change some obscure regulation most people don't even know about.

I would be down for the billionaires to begin to change the republican narrative en masse the way conservative billionaires have done in the past. Outright buy conservative media and then force them to publish increasingly progressive narratives while pretending to be conservative or moderate. Advertise heavily for raising taxes on the rich in red states by buying local newspapers, local politicians.
