isn't zoro already in that position? we've seen him take control before, though cant remember where exactly. Surely Hancock could become cleaning lady (smiles at Vanessa), since that will undoubtedly become her next fantasy, after feeding him.
Hmm, I wasn't much of a fan of Daz Bones, what could he bring to the ship? But an addition of Crocodile and Mr 2 would be quite fun, I'm sure Oda could pull it off if he wanted too. Plus, we'd finally have a logia on board, though I always hoped that would be Smoker, eventually becoming disillusioned with the WG and turning rogue, in Drake's footsteps. Which brings me to my next point, Drake should join the Sh's. Yes, it is a radical step, and very unlikely, but I would love ot see his T-rex zoan being used in humourous occasions with the other Sh's, plus his being a former insider could finally bring what the SH's nee dmost. knowledge about the world, they can't always rely on Robin having heard of something, and why isn't Nami readin the news regularly anymore?
So, in conclusion, Smoker, Drake, Crocodile and Mr 2 will join the Sh's after this war, and there's no way about it. Oda promised me. Plus, Marg will fall form the sky for no reason, and join too, since they need more girls onboard.
