how to determine the legitimate champion

this is my proposal to fix the problem of so many champions make only two sanctioning bodies and have only one champ per division per body they would be required to fight every 4 months it would solve lots of problems if they are injured then sanctioning body's doctor says when they fight fighters only have to have one mandatory's per year or one per body if unified the divison with three free choices for the other three fights only the free choices are to be on PPV as most mandatory's are easy fights keeps the fans happy this will mean that then we will have a more definite decision when determining who is the true champ of that weight limit let me know what you think would it work or would it fail
