It may be that this has been asked before, but if so, I haven't been able to find the answer. 
I want to try playing as England, Williem the Conqueror in 1066. Quite normal, he's Norman, so are his heirs, and most of the England is Saxon.
The thing is, I would like to somehow later, change my culture to English, and if possible provinces to. Now I could probably edit save game file, or something. But is there 'legal' 'in game' way of doing this. ?
