Just create a format where every win is rewarded if you dont like (quick) draws. Why would a spectator care about a game that has nothing on the line?

Just play every game Armageddon style. White gets some extra time, but draws are a win for black.

If you want to add an additional meta-game element, allow the players to bid for how much less time they're willing to take to play as black.
