I don't think the Sun Pirates are wanted at all ,now before I get bombarded with "iths seds dats ins de menga" posts let me just say that it doesn't add up that Jinbe's faction of the Sun Pirates are wanted yet it seems that Hachi isn't? I mean this is a guy who actually escaped from the marines yet no ones looking for him which was just two years ago. Anyway I'm pretty sure that by the time the confrontation with Big Mam is over the Sun Pirates will return to FI or to be more specific the now closed off Fishman District,highly doubt Oda did this for no reason,which will basically be their official hideout while they protect FI from the rookie pirates who come from paradise,under Luffy's Banner.
I'm assuming they left FI with Jinbe purely out of loyalty ,similar to when the members initially left the Fishman District because they wanted to protect Fisher Tiger. We have to remember that After Marineford, Jinbe was most likely in a similar standing with the WG to Tiger after he attacked Mariejos or maybe even worse since he was a Shichibukai who betrayed them,so it would make perfect sense that Jinbe decided his presence on FI would cause trouble for the Kingdoms Reveire ambitions ,so he left the Island with his faction following him out of loyalty and respect for him,not because they themselves are Wanted.
And if they are wanted ,then I could see Aladdin taking over the captaincy of the crew from Jinbe,this would basically bring the whole Sun Pirates story back full circle ,as the Original Captian of the crew was a former Slave & the 2nd one a Former Soldier. Aladdin happens to be both and a doctor to boot!
