Player Made Kingdoms (PMK's)

Currently according to Wurmpedia if you start a PMK you have to pay for a writ of some sort for 1 gold and you become an enemy to the template faction if you choose the same faction, in addition there is a member requirement.  Since we are a pve server there are no other factions and so by default if indeed you did decide to PMK you would become an enemy to Freedom.  I was wondering if there would be a way to start your own pmk without the pvp options.  The benefits might include personalized banners (maybe pick from a set of premade banners even?) the name of your kingdom, tower types(like picking out a diff type of tower from say mol rehan etc)  Perhaps with this system we could institute the "offices" that give you perks like court magus where you get double the favor.  The person who starts the kingdom could be king.  If multiple kingdoms are made you could be king of the north, king of the sea etc etc.  The king appoints the offices as the kingdom gains experience to open up more offices.  Each office within each kingdom gives perks, therefor there could potentially be 1 assassin for each kingdom etc.  

No idea how to implement this without turning it pvp probably need some sort of programming to change something around i have no idea.
