Hawkins is the only one who kind of makes sense as he isn’t yet on the Luffy Wank Train and has interacted with Law. Nobody else cares all that much about him except Kin, who is grateful to him, but clearly not to the extent that he is grateful to Luffy.
I’d personally like to see Law and Drake, not join up together, but start working with each other in some capacity in a sort of grey area between pirate and Marine. They both interacted in Wano, their backstories intertwine with each other. Law had a Marine mentor figure undercover as a pirate, same as Drake is doing now- hell, Cora might have been a member of SWORD, or the reason it was founded. And Drake’s dad is sort of an anti-Corazon.
