Re: Raftel
No. Well, All Blue may be near Raftel, that would make sense, since Raftel is a mystical sort of place, where all the weirdest and most wondrous stuff in the Grand Line probably is. But other then for Luffy, Nami, Robin, and Franky (you forgot him, DutchPhoenix, for his dream to be fulfilled, the Thousand Sunny must become a ship that could sail to the end of the Grand Line. In other words, a ship that could reach Raftel.) there's no reason for the rest to go. A medicine tree being there? I doubt it, I doubt there would just be some plant that could cure anything. Except for
band-aids, of course. And Chopper's dream is for him to be able to cure anything, not to find some medicine that would do it for him. And Mihawk isn't on Raftel, he'd be the Pirate King if he were, and he's not, because Luffy will be the next one to reach Raftel. Mihawk probably isn't near it either. When we last saw him, he was on Mariejois. Mihawk can be wherever he wants to be, there's no reason for him to stay in one place. Ussop can prove his bravery in other ways and in other places, so there's no need for him to go to Raftel to fulfill his dream. If Brook joins, then he won't care, he needs to get to Reverse Mountain to get to Laboon, not Raftel.
