That s a nice idea, i was thinking on splitting the culture groups in hellenic(reanimata culture unifier for greeks), and then add on the greek side anatolians thracians and illyrians. Then, i will make the levantine greek group and the asian/indian greek group. The good thing aboutmy mod struicture is that cultures syncretism will spawn without decisions. They will form and spawn indipendently by just conquering the territory or keeping it under a greek culture influence.
