She can't go back to that because there's nothing to go back to, the joke played itself out ages ago, especially since pretty much every goddamn anime girl streamer since was copying Senzawa. If she tries to bring it back, she would be seen as a lesser Nyanners, and she wouldn't do that anyway because her humor developed since then, she's far better at absurd improv than out-of-pocket adult jokes, and Gura is better for that purpose, being a cutesy shark creature rather than a conventional girl.
And most importantly, unlike Ame, Gura can actually sing and perform, so she doesn't feel out of place in an idol company. So there's no reason for her to go solo.
