That's an iffy comparison though, since the Spanish Civil War was essentially a military uprising. There were professional soldiers on both sides, most of the 'mob charges' tended to be those of Republican militias against hardened Nationalist veterans of Morocco.I'm going to be a contrarian and claim the SA could have won, under the right circumstances, especially if they strike first, enjoy the element of surprise and benefit from confusion among Reichswehr. Hell, some army units might simply obey 'orders' and stay in their barracks.
In any case, see the opening act of the Spanish Civil War about how a professional military can screw up.
Speaking of which, nobody seems to consider that an SA powergrabbing attempt might give us an early-access beta version of the Spanish Civil War, but set in Germany, instead of a clear-cut result one way or the other...
