In your opinion how well would Jai Opetaia do against Daniel Dubois & Agit Kabayel at heavyweight?

Jai Opetaia has been pretty vocal on a numerous of occasions about wanting to try and get a fight with Oleksandr Usyk at Cruiserweight before he eventually retires, but unfortunately for him that is very likely not gonna happen as Usyk doesn't seem interested in going back to Cruiserweight plus he has fights available at heavyweight that are more significant & is only planning to fight 2 more times before hanging up the gloves.

The only way I can see Opetaia getting the fight with Usyk is if he moves up to heavyweight which he has stated being open to and fights either Dubois (If the Usyk rematch falls through for some reason) or Kabayel, since Dubois currently has The IBF Heavyweight World Title and Kabayel currently has The Heavyweight WBC Interim Title making these 2 the most likely fighters to be Usyk's last 2 opponents unless they end up losing beforehand.

So if Jai was to fight either in an attempt to bag the Usyk fight how do you think he would do?
