Time to go scorched earth on the GOP and start digging up dirt on them - it’s the ONLY thing they listen to.
Given the number of high ranking GOP members who have resigned after minor scandals, at which a ‘Rat wouldn’t flinch, your suggestion makes sense. Some of ‘our’ RINOS may be replaceable by the end of the next midterms via standard measures: retirement, primaries or (in the case of McCain) divine intervention. Collins has talked about running for governor of Maine; I don’t know if she can do that and keep her seat. But many are ensconced against standard measures until ‘20 or ‘22. Any we can chase out now we have a chance to replace with better sooner.
