If we wanted to make monarchies function more like the historical examples (England and France in particular), that'd actually be the best way imo. Have the King also be Duke of the Capital.
I agree. Put those two together and you have the security to face down opposition and actually lead your country as a true monarch, rather than a figurehead or Ambassador with a nicer title. It is being done too, in some realms, but I do feel that it would be better were it a more common trend.
