Perhaps, but may I remind everyone that the year following the restoration there's the crash of 1929...not to mention Hitler's massive support, most of which he got after 1929...and at their height the SA had nearly 3 million men (not sure)...more than the Reichswehr (100,000) and the Freikorps, of which the strongest had about 500,000 at its peak...
And that's without considering the influential Social Democratic Party and the Communist revolutionaries...
Now lets say Hindenburg, the Junkers, the conservatives, the Military-Industrial Complex and the Right-Wing Freikorps support this, with the SPD, the KPD and the NSDAP opposing...
We either get a civil war or a left wing Nazi Revolution led by Rohm's SA...
Now, if we can get Crown Prince Wilhelm in front of a Harzburger front in 1932 instead of this idea...well, just sayin'...
