I dunno, I think the prospect of Frelick LF, Mitchell CF, and Weimer RF is awfully enticing. That's a GG-level outfield. Obviously one of those spots would go to Chourio, but if Weimer doesn't pick up the bat, he becomes a platoon piece/defensive replacement for CF/RF.
Regardless, there are plenty of ABs to split between 4 OFs, assuming Yelich becomes primary DH.
If Yelich could somehow play a mediocre 1B it would solve so many problems.
