In Hollywood?
Also idk I'm not getting the sense that there's a large extremist contingent of SAG lol Even that letter last night was extremely, extremely vague and not exactly screaming "GIVE US THAT REVENUE SHARING FROM THE STUDIOS!!!".
They weren't explicitly asking for anything in particular, and it does lead me to believe that they'd probably take what Duncan and Fran end up considering a "fair deal" unless it's a god-awful one which at this point I really, really doubt it'd be. The strike has had enough of an effect I do expect that if a deal gets made it'd be one where the studios conceded enough to declare it a victory.
I get the scenario you're proposing but it's so unlikely it's not even worth the stress of entertaining it.
