I think that if we agree on a certain scenario as work hipotesis we can start to look for solutions.
I share with you the result of the analysis about places.
I enhanced it to includes South germany, as suggested by Michael.
The actual result is that South germany with 57 points is the second best option (more point worse).
The 2 major pain points are the Interstate war and mass migration of popolation.
I'm open to your inputs and comments
