Interestingly enough, it could look as the situation after the
peace of Antalcidas, after that Attic hegemony was broken and that Persia not only took back Ionian coast, but greatly influenced helladic politics up to the point its gold managed to crush or found foes and allies, or even to threaten the formers of invasions.
Basically, you could end with cities and leagues being Persian vassals, with a leading satrap somewhere (probably in Thessalia), keeping some quite large form of autonomy as long they pledged alliegance to the King.
Depending of Persian rulers and satraps skills, the situation could last as Antalcidias' Peace OTL, or break out after a series of rebellions (the latter being less likely as time pass).
Interestingly again, that would certainly mean even more greek influence on Persian military techniques and cultures (Greek fighters being renowed as mercenaries already IOTL and much used by Persian rulers, governors or claimants)
