See, I think IF this were to happen, it would more be for 1B and having the ability to back up/play CF. Certainly he can play in a corner as well, but I don't know that Kepler would HAVE to go.
It also, arguably, would make it easier to trade someone like Wallner, or Kirilloff, or a few others for a starter.
But yeah, I don't see it. Not even sure he would want to play here. Fun to dream though.
