About the banning, I reckon it would be ok, although considered extremely bad taste. I can't imagine a publisher taking the risk. However, it's forbidden to use the swastika at all, in any context (1), so the image on the title page would have to be changed. The book is also not shown in the German Amazon search. (Yes, I'm German.) Sounds very interesting though!
(1)(there have been left groups with emblems with a crossed-out swastika having problems in court for this)
