I doubt Jinbe will join, especially with him telling Shirahoshi he would take away the burden she'd been carrying so long. As with every other SH, other than Robin and Zoro, Luffy has mentioned what he wanted earlier in the arc, needing navigator, doctor, cook, etc.... At the start of the FI arc he mentioned that he wanted a pet, so I think that Surume is the one joining. Surume has a purpose to get back to his family and I think before that he will want to have a little fun with the SH.
