Those sorts shifts didn't happen every couple of years, and they weren't methods of control for an empire. In an independent city, sure, there might be civil strife, an oligarchy takes over, and a year later they're overthrown for a democracy. Sure. The Romans, for instance, gave many cities nominal independence at the start, and only "Romanized"--if at all--much later.

Your city should change to it little by little, from different rule to another rule, eventually being considered as "homeland" for nation rather than being considered as "homeland" province ones your troops storm the city.
I'm not sure I understood your first bit there. And I follow your thoughts that you want a homeland province everywhere, but I strongly disagree. You may want to take advantage of the trading experience of the local population, or they specific military traditions of their people. If you install a 1 or 2, you--at least should--lose those advantages.

The 3 and 4 types should be viable options for rule. If you take a well-developed city, you shouldn't have to spend 20 turns making it a homeland. You should be able to install a 3 or 4, and just let the native people do their thing and you reap the benefits with minimal effort.
