I'd play the Airline, keep the K-200 and chip the Devo guitar.
The Airline is just a Les Paul with a weird shape body and less controls. It's made out of wood instead of the plastic the originals were made of. I'd play it to see what it sounds like, but I don't need it.
The Devo guitar is also just a Les Paul with a freaky cutaway. Don't need it. Into the chipper it goes.
The K200 has a couple things going for it, for me. It's a hollow body with D'Armond type pickups, which would be a great tone I don't really have. The Bigsby would restore some of the sustain normally lost to the hollowbody and give me some articulation with an easy vibrato.
