I hope Paulie and Franky both join. I can see this situation unfolding in Water 7 after they escape the Buster Call.
The SH are waiting in Mugiwara, hanging around with Iceburg and stuff while their ship is being built. Iceberg, Franky, and Paulie are all now working on it. It seems that Paulie is going to stay with Iceberg and Franky leave while Zambai becomes the new "Franky". I can see "Franky" being a title for the underground leader of the Franky Family. A week after the log resets, their ship is ready. Late at night, Iceberg is in his office talking to Luffy when his new secretary tells him that people from the WG are here. Luffy hides behind a closet and Corgi and some others come in. They apologize for trying to kill him blah blah blah and stuff and reveal some new WANTED posters and mutter some words that Luffy can't hear. The WANTED posters will be issued tomorrow morning so no one knows about them. After they leave, Iceberg first shows them their new bounties, and reveals a bounty both on Franky and Paulie. Iceberg tells Luffy that the only thing keeping Paulie in Water 7 and not with the SH was that he could be Iceberg's apprentice, but now he can't because he is wanted by the government. Iceberg writes a note and gives it to Luffy, telling him to find Paulie and give him the note. Luffy looks for Paulie all night and doesn't find him. Right as dawn approaches, Luffy finds Paulie hiding from loansharks. Luffy then gives Paulie the note and explains as best as he can to what is happening. We then get a scene of the rest of the crew and Franky wanting to leave Luffy behind because he is late. Luffy and Paulie then sprint through the crowd, past the loansharks and when the loansharks try to block the way to the ship, Luffy and Paulie use a combination attack, Gomu Gomu no Lassoo Rope, to propel themselves above the rest of the spectators, the loansharks, and onto the new ship.
