question about campaign map files

[cruach]

I want to play this mod in smaller map, such as vanilla's map.
So I copied vanilla's campaign map files in world\maps\campaign\base and \imperial_campaign and imperial_regions_and_settlements_names.txt, but I was kicked back to menu.
I checked log, and found errors about some units that deleted from vanilla, so I remove all such units from descr_strat.txt but it still dosn't work?
Could you please tell me if there are any more files which are related to campaign map in this mod?

You'll need to redo all the cities, region borders, rivers, campiagn script, events, sounds and so forth

I hope you get the jist of what I'm saying here...
