If it is Gaban, pretty sure he is gonna jobbing. He will pull the reverse of Sabaody Rayleigh.
The world is now bigger in Elbaf than in Sabaody. The crew is much stronger than 2 years ago. The enemies are also stronger. And Gaban is basically inferior version of Rayleigh, the Jinbe equivalent compared to Rayleigh's Zoro.
Gaban will be hypetool to Elbaf's main villain, only for Straw Hats to save his ass.
Reverse of when Rayleigh saved Straw Hats' asses from Kizaru.
