Should a champ be able to jump to a different weight class I say yes, but with limitations.
If a div has a clear contender he shouldn't be bypassed[ Weidmen, Hendricks ect...]
Should be requrements to holding a belt must be able to defend a certain amount if not give up / interium belt.
I am more for catch weight were the title isn't on the line just legacy.
I don't believe a fighter able to win two weight class's would be able health wise to properly defend there belts for more than a year.

I'm more for if you change class's [ without fighting in that div to earn a shot]and beat the champ now you earned a chance to fight for the belt.

There's a place for vanity fights, but the UFC has lost the prespective of how and when to use them.
They just need a basic guideline to follow as each would need judged differently.
