1) That would require three of the current factions to be sacrificed. 2) It is not possible to properly simulate civil wars with the current rebellion system. All you get is the occasional general rebelling, not a real civil war, and I'd rather have no civil wars than unrealistic ones.

Incidentally, Sertorius' fight in Spain was an extension of the civil war started by Marius and Sulla.
