I also don't think it's too viable given the roster construction. The main reason Cutch would do it is that he might be in a situation where he doesn't get much of a better offer elsewhere and as far as I understand it, he's never moved his permanent home away from Pittsburgh. He's still good for some power and I remember reading that his sprint speed was still impressively high in 2022, even if he doesn't offer much in the way of plus defense.
I doubt we are paying Santana 6.75M to not play nearly every day, but at the same time, he is a veteran player. There should still be enough playing time to go around with Choi/Santana/Cutch being in the DH role sometimes and Cutch being a 4th OF type. Where it gets fuzzier is if Cutch is looking for nearly everyday playing time. As it stands, Andujar also figures to get some DH and corner OF action, and I presume the plan with Joe is practically to platoon him with Suwinski. In any case, other than Bae and Andujar, none of these guys are too viable in the IF (I guess Joe could be third on the 1B depth chart).
If Choi basically never bats vs. LHP and Santana is a little bit more like a 2/3rds of the time player (unlikely based on his career and the fact that he signed so early), there's a little more room, but I don't quite see it unless Bae is more of a competitor with Castro for 2B than someone to pencil in as the LF/CF. I think that's a possibility -- i.e. that neither Castro or Bae have a spot locked down and will win one in spring training, with the other potentially being optioned -- but not something we'll know for a while. Besides nostalgia, I think the main upside to Cutch is veteran leadership and someone who can likely be counted on for 15-20 HRs, though that likely goes down if he's not a full-time player.
For me, the tldr; is that Cutch would mean putting some strain on prospects to earn spots (which I think is ok) and being ok with DFAing somebody like Andujar or Joe if they are underperforming (which is also ok). I don't think ditching Cutch will be an option, and at the end of the day I don't think the front office wants less flexibility.
