Amigo, Switzerland was not an active combatant in WWII, though they were in many cases pro German, intercepting wayward and damaged US bombers over their airspace to land with the crews being interned as pows for the duration of the war. Some of the Swiss prison camps were reported to be much worse than their German counterparts and were in some cases operated by Swiss Nazis, not to mention the complicity in robbing European Jewry.
You can make any skin you like and fly it offline. I'd be pretty surprised if they changed their policy.
