Should I do this?

I have a multi time undisputed world heavyweight champion at my gym. He’s 49-1. 19-1 in title fights. He’s made over £500 million through this career and is 33 years old.

I also have a 19-1 undisputed cruiserweight world champion at my gym who’s 2-0 in title fights and only 28 years old.

Do I move the cruiserweight up to heavyweight and have the biggest showdown in heavyweight history?

Yes… However, you can’t make fights between fighters from the same gym…

Not to worry not from the same gym I current have 5 active gyms all with 24 fighters

I personally would be tempted to drop a belt and let the Cruiserweight fight for it. Then have the undisputed fight between 2 current champs.
