Nor has it been decided what this rules looks like and who (if any) will control him - so for now, at least, I recommend keeping these characters out of your creations and focusing on your own character.
This is just a suggestion, but I think the in-game leader of a province could be the PO's character? That way, it would sort of be connected to who actually runs the faction. If there is to be any such thing, that system (and possibly the liaisons' characters, too) could give a minifigure cast to take part in royal councils, meetings and decision. On top of that, I think different in-game titles should be used for each province's leader and liaison, to mirror the different cultures.
