The problem with revolts is that if they border a super power they will get annexed and there is nearly nothing you can do about it. So here is my idea: Give them an event upon being attacked, to ask for a white peace(or defeat, not sure) with his liege, no matter the other war participants and how well the war is faring, as that is most likely better sometimes than being holy warred by the Fatimids. The war with the foreign power would then end inconclusively.
