Have you downloaded the free campaign guide and looked through it yet?
I saw a section several pages long talking about whats things you would need to adjust and be aware of to modifiy it to fit else where. I don't think it had a specific use these countries and cites in FR but should have enough to make it fairly easy to work in somewhere.
I'm just running it as a stand alone campaign at this point so I didn't look to close at that part as I'm going to use everything as written.
