Boss Vs Boss Gauntlet / Currency Gambling

After seeing the Boss Vs Boss: Rathbreaker Vs Mighty Silverfist video, it would be super interesting if there was some type of currency gambling system incorporated into it. Especially if we could get some boss modifiers into it or even get Uber bosses vs each other.

I'm envisioning a boss vs boss gauntlet every league where players can place bets on their favorite/hated bosses. In terms of cadence there would be a boss Vs boss fight every week until the league is over.

A random and silly thought I thought would be interesting.
