I don't see them thinking outside the box and even entertaining this idea.
Heck, I think Chapman/Hamilton might get it done. You might have to add Cingrani or Corcino or Stephenson, but I think that would get it done. The Fish might want an OFer to fill the void of Stanton, possibly Heisey.
If that deal is made, I re-up Choo on a multi-year deal and the team is set for years to come offensively, and the starting rotation is the same as last year's.
