Will Senate make a completely new, "moderate" bill with ok CBO-score that they will send back to house? Why would house vote for it? Is it realistic?
What would be a 'moderate' GOP healthcare reform bill even look like at this point? A big part of the reason their 'reform' ideas are awful is because Democrats already took the best ideas from conservatives and put them into the ACA. Whether or not Republicans want to admit it, ObamaCare is their type of reform (although ideally I'm sure conservatives would prefer no reform at all). Everything else they've proposed is either marginal changes or straight up extremist garbage.
This is part of the damage that partisanship does. It is true that a lot of the ideas behind Obamacare were first forwarded by Republicans, but because Obama chose to advance them (as an attempt to be bipartisan after he met fierce resistance for a more left-wing program, I would note) they were abandoned for that reason alone.
