I think only a mad man, like Hitler would be able to get the Rhineland, Austria and Sudetenland in the short timefrom Hitler got them. Hitler was playing woth fire, hoping for a war, he only got with Poland. German leader that are more sane than Hitler (or less insane) would not take the risks Hitler did. So I suspect that it will either take a lot longer to annex Austria and Sudetenland, or it won't happen at all. Also without war, I doubt anyone would be able to get West-Prussia let alone Posen from Poland, so I think annexing Danzig would be were it all ends. Although, maybe after a couple of decades, with the rise of the Communist menace in the east, western Europe might be willing to look away if a fascist Germany, that proved no threat to the west, tried to strengthen it self from the dangers in the east by annexing the lost parts of their former empire.
I wonder if Goering would try to reclaim south Tirol, Elzass-Lorraine, Eupen-Malmedy or northern Schleswig. All of which would get Germany into a war they should not want to get into.
