I'd say he's potentially joining given the fact that Luffy's judged him well and Luffy is a perfect judge for someone's character, the literal only person to fool Luffy is Kanjuro and that guy was 50 levels of 10 dimensional Chess deep.
The major issue is he's quite literally too big for the ship. Unless he can shrink in size with his Devil Fruit there's gonna be some shenanigans even getting him aboard. He's the Ridley of One Piece is what I'm saying.
Bonney is a no-go, she's a glorified arc princess. Vivi is 100% rejoining or getting possessed by Imu.
