Yes. If they got three different town to honestly claim their name, and the lynch went to a town player and not one of the neutrals.
The neutrals they didn't even know existed. The neutrals that could have been among the players to claim.
Like. I'm not arguing that town couldn't lose majority perilously quickly, but to think that scum could know to leverage this into functional majority not only requires that the neutrals decide to side with them but that scum divines that their are a total of 8 non town players.
And due to Wario, there's a chance they'd get lynched anyways.
And Bowser JR has zero reason to agree with a plan that will prevent his victory, which requires nearly 3/4 of all players dead. He outright needed at least one scum dead, and if only one then both NPCs not Bowser. So he would have no reason to go with.
And Bowser himself, meanwhile, may need to convince them to lynch him and not cooperate with their schemes, because if any of those three nightkilled were Mario he's now a Jester.
