The closest that we can see the odds in my opinion is Tapales, another good Filipino boxer. So the plan is as we have heard is that the winner of this fight, vs Marlon Tapales next for unification.
So if that happens then we can compare at least what will be the odds for Casimero. As if we are just changing the name of Tapales here. So before we talk about Casimero vs Inoue or Fulton, we will see first Tapales vs Inoue or Fulton and I think it will be a great fight although going to be very hard for the Filipino as he needed all the tools to beat either boxer.
You are right there mate, WBA has given the clearance to Tapales to fight whoever wins on the Inoue vs Fulton fight, they have not ordered Tapales to defend his belt via mandatory defense so this action is good for the Filipino pug.
But for me, Casimero has the higher chance of defeating either Inoue or Fulton but he has to do his thing first (win every fight) before calling out whoever will be the unified champion in this division.
For his part, Tapales is already a big winner by just fighting for the unified belt as i think this could be the biggest purse that he will receive in his boxing career, that's for sure.
