Here's an example of a YouTuber doing exactly this - this one guy's channel is called "Unacceptable Fringe", and you couldn't tell by looking at his channel now, but he used to make home arcade videos. All these videos sucked, and he's such a narcissistic tard that he couldn't keep his Canadian politics out of his arcade gaming stuff. Nobody in that scene liked him, and even though he had a decently sized following, and got a decent amount of views, all these videos he made sucked, and he had an established reputation of being a cringy arcade YouTuber. Finally he just got rid of all those arcade videos, got rid of all arcade branding, and ONLY made political videos going forward. Now he's basically Canadian Quartering, and his channel has actually grown a lot. Not my kind of videos, but hey, this rebranding worked.
Sounds like a no-brainer for Nicky to just give it up and become Coomalot 2.0.
