Jinbe vs Crocodile actually seems promising
Hes considerably weaker than Mihawk by portrayal (atleast must be), thus he can't be an opponent for Sanji
To prove water isn't a problem to Crocodile anymore, facing Jinbei would be one of the best ways to show that, while forcing Jinbe to come up with something else
Jinbei would just need more clear feats until then, only defeating Who's Who can't be enough
Both were ex Shichibukai, both helped Luffy at some point in Marineford...

Other than that, Desert King vs Sea Knight is pretty dope
