I mentioned Hank Garland awhile back because besides being a famous country instrumentalist he produced a jazz album a long time ago called Jazz Winds From a New Direction that contained some of the most joyous and inventive playing I've ever heard. Tony Rice, although he only plays steel string acoustic seems like someone who could (and has) add something great to just about anything he played on. And of course Junior Brown with his guitsteel and his incredible country, blues and rock chops is way up on my list.
