Unfortunately, there isn't a chance this survives, especially if it's closed-source and for money. Discord doesn't allow third-party clients (which I swear should be a legal issue since it's a PUBLIC API but whatever), and Discord is known to aggressively block and prevent third-party clients.

If you want something that doesn't suck, look somewhere other than Discord. It sucks that it's so embedded into so many groups but Discord isn't a very friendly entity.
