Paying money to watch a restream of the same game is excessive (in terms of quality). Maybe there are some people in the chat who would do that, but fans of Heroes are not just in that chat.
About a year ago, I considered doing a series of streams based on the "king of the hill" principle – you play until you are defeated. Each game would have its own prize pool from viewers. This idea could work. I did something similar with Worms Armageddon and it was quite successful. But Heroes battles don't last for 2 hours. Therefore, viewers probably won't be able to watch the entire stream, which raises the question of why they would pay for it
