If I could do anything, I'd want to become a professional musician (along the lines of Seven Places, David Crowder, and The Almost) that recorded, performed, and wrote music that had both a Christian message and musical merit (the second being more subjective of course).
I am working on both points still, but hopefully one day I will be one of the artists people hear and think "wow that's a Christian artist? that's cool"....
