I would think if you have a Dictatorship the senate would not even exist. I would think of something close to the Tribes situation.
Well I don't think that the Senate should vanquish when you become a dictatorship, since Ceasar was a dictator too(for lifetime) and there still was a Senat. So it would be historically acurate to keep it.
Sure the dictator could have the possibility to stop the Senate once and for all, but that should lead to major unrests in your country. (stability drop to -3 for example, avoiding exploiting it: Just make it impossible to destroy the senate if your stability issnt at least +2.
But just keeping the senate would be also enough. Also a dictator in Rome was called in a major crisis, but only for 1or 2 years, then he normally laid down his privileges, which ceasar didn't do.
The Senate members should also loose loyality to you if you don't stay extremely powerful while beeing a dictator in a republic. Also the possibility for a civil war should rise heaviliy if you decide to remain a Dictator and don't return to the consul system. (Still depending on the Dictators skill, popularity, loyal units and powerful friends...)
But then again the Senate would have to be pretty powerful(while not beeing a dictatorship), to make a dictatorship useful.
Just suggestions and I would be greatly interested in what you think about it.
