I read a different post which gave me this idea, but I must credit the originality to Europa Barbarorum for Rome Total War. Here it is.
Since youve already created races and, according to all mythology and whatnot, some hate eachother and are clearly different, there wouldnt be a smooth transition if you conquer a different race. My idea adds on to your original idea of having race specific buildings, but it is to your benefit to destroy/upgrade these buildings if you are a different race/completely different culture. Upon capturing one of these cities, you must build a building (call it regional pacification or whatever) wherein your units are "scouring the city and country side putting down rebellions". You cannot build any other building in the city or build any type of unit until this is completed. After all, how can you successfully govern a province if the whole region is in anarchy?
An example:
Im an elf nation and I capture a goblin city. They're racial buildings are causing me unrest. If I cannot upgrade them, it will be harder to rule and I should destroy them (maybe getting production from the material or gold - call it pillaging). Before the turn is over I need to select the regional pacification option (lasting one or two turns) before I can do anything productive with the region. Since turns last anywhere 1 year to 50, this makes perfect sense as your own people begin to subjugate the other race.
this can of course be molded about to fit into FFH2 better but I hope you get the idea
