My guess:
Create a new city-style (Eastern European) for: The Huns, Russia, Poland*, and Yugoslavia*
The other new civ, maye the Assyrians
Sorry but having Yugoslavia as a civ would be a total joke. The country existed very short time and it doesnt have any kind of historical relevance.
Having Serbia as civ would make much more sense.
Anyway Poland and Sweden would be best Civs from Europe. They are distinct unlike Austria, which is pretty much little brother of Germany. Sweden and Poland have their own distinct history, culture and language. Austria would not be interesting Civ in my opinion. As a country Austria was important, but not as a Civilization.
