I wanted to write a bit about the Strasserite NAZIs, but frankly I couldn’t imagine them having any traction in any major German cities. It occurred to me, though, that Danzig would be the perfect breeding ground for that sort of ideology, what with the hatred of Poles and a feeling of betrayal (since many in Germany sought to kick the Danzig can down the road).Especially with the kind of actions they seem to be pushing for in Danzig here.
As for von Papen, he is someone that I always saw as gaining some power because he is slimy and connected, but lacking the sophistication to really become anyone influential or important. He sees himself as a harbinger of a new German era but lacks the needed skills. I absolutely see him getting angry and resentful and making a deal for power like he tried with Hitler. If the Nazis could outplay him, that says a lot.
Well he had already met Wallace and wanted to marry her. I think that his German sympathies would be less of a problem, but i also don't know how strong they would even be without Hitler.As for the mentions of Edward VIII I would say that while his relationship with Wallace Simpson was the issue that publicly caused the most problems, privately it was his leaning towards the Nazis that caused the real anxieties. It wouldn't take much for Edward to not meet Wallace and be cajoled into some more suitable match and pro-German sympathies are going to be less of an issue here. Basically as long as he restricts his behaviour to the sort of things the British press have long turned a blind eye to when it comes to the monarchy, then there's no reason for him not to become King.
One question is of course will he produce an heir regardless of who he marries ITTL?
I'm also not sure how much incentive he would have to restrict his behavior. He seemed as a person to be wholly incompatible with the way the British monarchy functioned in the 20th century. I personally feel that even here he would be seen as an undesirable option and that the attempt to marry Wallace would still cause pushback.
