That sounds like a fast ticket to banruptcy. if you have a wave of horror tubers what incentive do i have to watch one outside of "the best one" sure that problem still exists to an extent already but this idea just makes that worse.
maybe you could vary it up by having each of them cover different aspects so theres less overlap but it would still end up that they would cannibalize each others viewers till only one maybe two have any people left. and this is just one wave you want a whole corperation for this?
I guess if you stretch it Cover is the "idol" makers Ninji is the "casuals" but identify is more pronounced in the generations themselves. Myth want to be JP idols and presumably put in the work GAMERS are a close clique of friends ect.h
