The Kaiser's Restoration by 1936

In OTL, a majority of the officers and military leadership in Germany still held loyalties to the Kaiser and the German Empire of old. Suppose that sometime between 1929 and 1936, Hindenburg rallies these officers and those loyal to the old Kaiser in order to oppose Hitler and his Nazi party. If somehow this is successfull, how would Great Britain and France react to seeing the restoration of the German Empire? Would the Netherlands allow Whilhelm II to return to Berlin or would Whilhelm III become the new Kaiser? Perhaps most importantly, what would Stalin and the Soviet Union do in this situation? Would an alternate WW2 begin with a Soviet invasion of Poland or Finland? And finally, what is the fate of Italy? Does it go down the path of Franco's Spain?
