Only admiral fight I am 99% sure can happen is Luffy vs Akainu.
It's nothing to do with power but the portrayal Akainu got at MF.
First, he's the one who killed Ace. Not just killed him, but put a donut hole right in front of Luffy and mentally broke him.
Second, a big massive scar on Luffy's chest.
Akainu is the only character in the series so far who gave permanent scars - physical/emotional/psychological to Luffy.
Oda wouldn't have gone to such lengths with Akainu if Oda isn't planning to have him fight with Luffy.
This fight is happening. 💯
