I think that my Ghemor would ask the Federation for help...and I think the result is easy to foresee
He had no support from any part of the military after all--one part was The Directorate, and the other part the Mar'Kuu Group. If he had any supporting guls, it wouldn't be enough. So he might have a stupid idea of asking the Starfleet to help him.
I can only hope the Federation would refuse, but I am not so sure of that.
