Hitler's Maskirovka (Naming inspired by Life in Black

)
The plan is:
I was thinking what happen if Hitler know that Sea Mammal is a failure but still proceed in executing the operation in smaller scale not to actually invade Britain but to create the impression that the German Army is not as strong as it is in 1940-1941. The objective is to bait Stalin into thinking that Germany is weak and could be attacked earlier. (Enhanced by espionage such as moving troops from the East to the West and provocation) Whereas at the time same Hitler is planning a massive surprise for Stalin once he began his invasion to the West. (He recklessly invade without hearing the advise of his General)
Hitler uses this invasion to destroy Stalin reputation as the real invader gaining support from neutral states like Yugoslavia and Greece. There is no Lend-Lease for SU because of that reason also. Once the Soviet Army is destroyed in the border Hitler then continues on attack Soviet Union but instead of conquering land Hitler creates separate satellite state like Ukraine and Byelorussia (liberating the Baltic states too) in order to create a turmoil in Russia. To further create negative image of the Soviet details of Katyn massacre is released together with other things such as the Great Purge etc. Hitler stopped at the gate of Moscow demanding peace. Stalin is overthrown by Molotov or Beria which in turn accepts peace. The East is now secured.
Before proceeding further what do you guys think?
Situation as of now:
-Stalin would not probably attack Germany despite the intentional failure of Seaoperation and would prefer to stick with Molotov-Ribbentrop Pact.
The alternative is:
-Create huge provocation.
-Use Stalin pasiveness to conduct more comprehensive African Campaign and to increase German readiness for future Barbarossa. (1942-1943)
Additional change:
-Hitler replaces Canaris as the Head of the Abwehr and employ vigorous reform in the organization to increase its effectiveness and capabilities.
-The faulty Enigma is discovered leading to a complete encryption system change.
