I don't think that can be forced. I was part of the shinna stream, where she managed to use the raid to use it to slingshot her growth. Shina, by that point, had bounced off the bottom of the barrel and was using (and still does) her chat as a crutch to get through shit. She was about to sign off, but once the raid happened, when an extra hour, and immediately gained 1k subs. I doubt that the growth would have happened if both of those events didn't occur, as they need to be willing to put in the authentic effort to integrate them.
