It's possible. I suppose the DNVP might pull Goering (a dashing veteran pilot with the Blue Max ... provided he goes on a diet) as the public face of their campaign. As an elitist group composed largely of nobles, they had quite the problem having the kind of wide appeal that the NSDAP managed to gather. Or possibly von Schleicher (if he still winds up in charge), trying to shore up his flagging support does the same.
Of course, neither of those would be quite Nazis. Fascists, certainly. Militaristic, monarchistic (to an extent, they were privately so, but monarchy was unpopular in Germany at the time). Smarter than the Nazis ... or, at least, not the kind of fanactical believers in their own propaganda. You might get a war still (probably would, in fact), but not WWII. A conflict with an isolated Poland or with Italy over Austria and the Balkans.
Goering didn't get really fat until after he got in power. I think he got really bad in the late 1930s and certainly in the early 1940s when he started emotional eating when he lost Hitler's favor.
