I think that Smoker is a high chance posibilite, i mean, whats the point of bring Smoker at this point in the plot? He is just here, and have a long time with the crew. He is a Logia User, color theme White, good design, ex-marine, strong personality, decent level of power, have Hakis… and he can leave behind tashigui Captain of G-5, like Jimbe do with the sun pirates.
