If the Marine Corps wanted the A-10 capability, it would buy a similar platform.
Not too long ago they were thinking about a yet another deal to aquire some A-10's. I recalled so of that info going through your neck of the woods in the last proposal I heard about (although from what I know this last one was much less formalized that others have been). The reasons the Marines don't just go and buy something similiar is enough for at least another thread.
I am certainly not married to the A-10. I do like it because it is a jet built for a specific mission, not a jet "built" for every mission.
Above that, though, my issue is when the AF--or anyone-- tries to come up with a new (old) idea and wants an excuse to buy a new plane that might not be as capable as the one it currently has to do this new (old) mission.
But if we were to start "I love" threads for those two aircraft, I could be talked into joining the cult. I once saw a movie with some F-14s that was really cool...
