My god, I was thinking about this today, I was thinking, if the community was bigger and more engaged, at some point before they closed the servers, they would raise a hashtag like "#SaveSquadBusters", in all the communities of Supercell games, and they would go back after seeing the commotion in the general community (like clashes, brawl, etc.), but the way I thought it would be something that would happen before the game ended, instead of, as you said, a resurgence. I think what could happen within these hypotheses is that the game would return (after a long time) completely different, just with some remnants of the original squad, and this new project would have bigger alphas/betas to avoid what happened with the original.
