Thinking of it, the solution is easy. Just have every good candidate join the straw hats in one mega crew (Wizaru, Waribou, Carrot, Yamato, Bonney, Stussy, Lucci, Smoker, Hancock), that way the merchandising possibilities go up, the coomers get extra material, and the final saga is even more epic (Shueisha, gimme a call, I'm cheap).
