I hope no one is dumb enough to start an eSports Org right now. Now, doing some weird hybrid Pro Streamer operates as a Vtuber thing could work. Former top pros that stream is a big market. In fact, quitting a top team and going full time streamer is normally better money than all but about 2-3 guys in an eSport make. (This is known as "how much money did RTZ lose by not streaming once a week?".)
Now, a harsh reality of pro players. They have almost no personality for streaming. They're super quiet, incredible introverts. The few that aren't have almost all gotten canceled because they're used to an environment that's hyper competitive and extremely toxic. This is actually why Pro Teams lose so much money. They can't do Branding / Promotion because their best players would rather sit and play for 14 hours than do 15 minutes of work to make themselves 10x the money. (A lot of them are good at games but otherwise rather dumb.)
You can see how the South Koreans have managed this. They actually force the guys to get media training, and, even then, only a couple are ever allowed to be the "face" of things.
