OOC: To start technically he can call himself the Emperor of Mordusia, but it would be a Pretender claim. There are several people who claim to be King of France or even Emperor of France, but as you can see they have no power and are not even mentioned by the French government because they are not part of it. So you can not really control whether or not he/she calls himself/herself the Emperor/Empress of Mordusia. Also a reminder while in the game George is now Emperor, we are keeping this during the last months/years of Henry's rule for realism.
IC: The issue is that you argue as if the Emperor has power to begin with, but again he does not!!!! I shall say it again; the Emperor has no power in Mordusia. Your elected Viceroy who yes represents the Emperor but is not controlled by him, runs the nation as the people who elected him see fit. You are already a republic, which gives honor to the Emperor by giving him the status of "HoS". However, in reality this is nothing more than a de jure title, for the real holder of that power and the de facto HoS is the Viceroy.
So after you take that information over half of your argument falls apart. Now you ask why you can not leave a personal union. Well let’s be frank because it is overthrowing the government. Again, it does not matter how you word it the end result is the same, the current system will be overthrown and that is destroying not only that section of the "Empire" but it is also breaking all ties you share with Alduria and Luthori. Over what again? So elected officials can rule? So the people have a say in their government? The problem is they already do and you already are under the rule of elected officials.
So really the issue is at heart is you want your de facto HoS not representing the Emperor in theory. The best way to fix that and solve all these issues is to simple make the Imperial and Executive branches separate like in Alduria. Then you can not claim in any shape or form the Emperor is manipulating the outcomes, and that the people are ruled by a truly democratic leader, yet they are already ruled by one now.
This entire debate is stupid!!! For the only thing that will change is the name of the nation, maybe the flag and anthem, and the title of the Head of State.
