i want to make a new business model
That's not new. It's about as old as there is internet and games that can run in a browser. Armor Games was started in 2004 for example. In the physical world, it is a lot older.
That you try to enlist "indie" devs is a technicality. There is loads of such sites. A lot of them with some blockchain gimmick, since you cannot really collect pennies. Oh, wait, there is all the in-app purchase games, mostly on mobile.
Anyway, there is nothing new about that business model.
