Honestly after seeing Wano, I think Kuzans role in the Blackbeard Pirates is just a very straight forward: He’s Blackbeards ally.
He doesn’t have an ulterior motive or secret agenda, he likely joined up with Blackbeard for the sake of his own dream and after the World Government backed a psycho like Sakazuki over him, he very likely lost faith in the WG.
As such, I think he’ll be the “Big Mom” of the Blackbeard Arc (just much more capable) in the manner that he’ll fight someone not in the straw hats but is allied with him.
Best options for who would fight him would be one of the following
Luffys Pirate Rivals:
Kid
Law
The Revolutionary Army leader:
Dragon
The marine who’ll become “Luffys Garp”:
Smoker
Coby
Or like in Wano, two people will team up to fight him.
I just think with Oda looking to wrap up the story, he likely doesn’t have any plans to create a Kuzan side plot outside of his reason for joining Blackbeard.
