I haven't had a char be ruler for 4-5 years now so the custom names thing is quite new to me. Can you always change the names of the 4 council positions when you're ruler or how does it work?
Also, government system. You need a rebellion to change the official stance from i.e democracy to monarchy, but can you change if the positions are elected and how often (or not at all) without a rebellion?
I.e a monarchies can be quite different from each other. One can be that ruler/judge is elected only once and general/banker as appointed. Another can have that ruler is elected once, judge quarterly and general/banker monthly.
Do you get what I'm trying to say? I'm not completely sure it will come across
