Here's a thought exercise: if the Nationals considered an offer to trade Corbin to the Dodgers straight up for Bauer this winter, who says no?
Bauer will probably never pitch in the majors again, and his contract structure means he can opt in twice and be paid $64 million over two years. The Nationals would be responsible for that.
Corbin can continue to pitch. He might even be somewhat fixable to the point of providing positive value, although likely not much. He's owed $82 million over 3 years, which would save the Nationals actual money, but save the Dodgers as well because he'd lower their tax bill by a huge amount versus Bauer over the next 2 years. So the question becomes whether Corbin might generate $18 million in value over the next 3 years: that's around 2-3 WAR.
This is probably only a sandbox exercise because MLB is likely to suspend Bauer without pay for a significant portion of that contract, and I doubt the Nats would take on Bauer's name even in a transaction in which they made clear he'd never play for them. You could of course structure a trade to fix the first issue.
