If you havent already read the interview then you ought to, republics are about more than just elective mechanics. Almost none of the other money-&-trade-power-centric mechanics would fit Morrowind in the least.
Well, yes, I have read the interview. I was just htinking about the succession and assuming the republic succession can be applied without the other mechanics (as currently there is already an "open elective" that republics use), not the other mechanics.
