Maybe this sounds naive, but I think it would be too much, even for FA.
To punish Everton properly for 1 FFP breach, and possibly to slap City on the wrist for potential 115 breaches.
It would completely destroy any hint of fairness and same standards for all in PL.
As long as Pep/Haland are here, those charges aren't sticking. The only small reason to be positive here is that they can't appeal whatever decision they get like they did with their recent overturned ban.
Any "integrity" was out the window with Chelsea, compounded with City and now made a bigger mockery with Newcastle.
