It's a bit difficult with how the story's gone post-TS. I still see BB as Luffy's ultimate final rival due to his intro and how similar they are, being the good/bad versions of the same ideology. Akainu killing Ace made him a Big Bad but could be Sabo's fight... Shanks is Luffy's PK fight, maybe on Laugh Tale, Mihawk for Zoro's final fight. Im is a weird one, we still don't know shit about them but I see it being someone like Dragon's fight potentially.
Worst case scenario is after the story ends we get a bunch of these match-ups (Shanks vs Luffy, Mihawk vs Zoro) that we never actually get to see onscreen.

Second, roger failed to achieve something after becoming PK - so it's clear story goes beyond getting one piece and has to do with wg.
Akainu vs sabo - Alainu and BB are goated antagonists. Akainu gave perma scar to luffy and killed ace right in front of Luffy.
If anyone deserves to take on Akainu then it's Luffy and not side character like sabo.
BB vs luffy will happen for pk war.
So order for me is BB - > Akainu -> IMu
Shanks vs BB makes more sense than shanks vs luffy
Not sure how mihawk fits in
Looks like Blackbeard may be clearing the board before fighting Luffy while Morganβs is trying to ignite war between Luffy and Akainu
So likely Akainu -> Blackbeard -> Imu
