As of now most of the big Nazis from OTL are nothing now, many either had just joined the Party or had not yet. At most Röhm is aligning himself with militant communism while Goebbels is a Communist propagandist and Göring is affiliated with the DNVP.
I could see Goebbels potentially going Red, but not Röhm. All his rather vague speechifying about the 'second revolution' wasn't an endorsement of communism or class warfare. He wanted to throw out the old elites in business and the military and essentially give the SA the status the SS, to a large extent, ended up being able to attain, but he hated 'Marxists'. Hell, based on Peter Longerich's study of the SA, he seems to still have had monarchist sympathies in the 20s on top of his right-wing nationalism. Indeed, he appears to have had ties to the Bavarian crown prince Rupprecht.
In 1919 he was part of the Freikorps Epp under Franz von Epp, which was heavily involved in the violent suppression of the Munich Soviet Republic, and continued his career in the Reichswehr. At the time he met Hitler, he was still working with the Reichswehr as an officer. He was an intermediary between the army and various right-wing paramilitary groups, and informally known as the 'machine-gun king' and an important alliance broker. So he was already active in right-wing politics in post-revolutionary Bavaria by the time he met Hitler in OTL.
