What about resigning Nunez to share time with Hanley at 1B/DH? I don't think he's ever played 1B, but I'd imagine he can handle the basics of the position. He'd also give them flexibility with his ability to play 2B/3B/SS to give guys a breather. If he stinks at 1B, they can look at playing Hanley more and keep Nunez to DH and backup IF.
Something like: Nunez (1B/DH), Beni (LF), Betts (RF), Devers (3B), Hanley (DH/1B), Bogaerts (SS), Pedroia (2B), Vazquez (C), JBJ (CF).
Another option: Trade JBJ for someone like Brandon Belt and sign JD Martinez to play LF. Not sure if Belt is the guy they want, but look for someone like that who they can plug in at 1B for a few years.
That would result in something like: Bogaerts, Beni, Betts, Martinez, Devers, Ramirez, Belt, Pedroia, Vazquez
