I would be fine with Kalish platooning with Gomes. Gomes will probably gets some starts vs RHP at Fenway and is the starter vs LHPs, so Kalish is a good fit for that role IMO. I would rather have Kalish there than Abreu, we can't wait for too much longer on Kalish. I'd want to know if he has a future here or not.
I'm a Berkman fan, but doubt he would sign here to platoon in LF. It's also doubtful that his knees can handle 1B every day.
