The most important thing would be making sure that people in power keep teaching their underlings how things should be, in order that everyone is well aware of the structure and the uses of the realm. It is pretty easy in bm for two realms that are very closely tied (perhaps a colony and motherland) to separate in time, just because no one takes care to explain what is their history constantly.
That is indeed correct, 'tis why I mentioned in my post that the majority of the idea will depend on the players. I think we will need to hit all our nobles with heavy propaganda about the Lurian Empire, which means everything from bulletins, wiki pages, newspapers, Kings and mentors. If everyone will really dive into their roles I think this might work well and we manage to create "the Lurian way" and a "Lurian heritage", which will hopefully be passed along to new players.
