Why would the US agree to any of this? The Soviets blockaded Berlin and had established Communist puppet regimes over all of Eastern Europe, the State Department was scared shitless that they'd continue to spread Communism westwards, which lead America to start the Marshall Plan to economically prop up Western Europe. You'd have to radically change the thought behind postwar Anglo-American foreign policy, which would have to be done by radically changing Stalin's vision of a postwar world, which was a ring of Soviet satellites between Germany and Russia that would serve to deter another German invasion of Russia (the Germans had invaded twice in less fifty years, so Stalin was justifiably anxious of a resurgent Germany invading Russia for a third time).So best case Soviet “victory” scenario would be that NATO is abolished in continental Europe or never formed, Western Europe joins the USSR in a continental collective security agreement, and any remaining COCOM trade restriction between Western Europe and the USSR are curtailed or abolished entirely. This satisfies the USSR’s mid-term goals - European peace and security and unrestricted access to imports of advanced technology from the West.
I don’t think this would grant economic stability to the USSR, but it would allow it to reform under much less “high stakes” circumstances. On the other hand, increasing economic and political linkages between Western and Eastern Europe would likely lead to the reform or collapse of “pure” state socialism much faster. So by the 80s/90s much of Eastern Europe and the USSR would be some form of market socialism, with some countries on the very liberal end (Czechoslovakia, Hungary, Poland) and others taking a more moderate track (The USSR and Romania).
Germany, I think, might reunify if the USSR is willing to countenance a neutral and capitalist Germany as a fair trade for a collective security agreement with France/the UK which excludes the US.

A earlier unified Germany is, on the other, theoretically possible. I know Stalin offered (and Beria planned to offer) a unified neutral Germany but Adenauer and his CDU (and the SPD for that matter) distrusted the offer and turned it down. Plus, by that time, Western Europe had already signed on to NATO and gotten the ball moving on the Pleven Plan, a plan to unify Europe's militaries. The only other offer I can think of was Ludwig Erhard's plan to simply buy back East Germany, which was also, in theory, possible but also highly unlikely.
The Cold War was unavoidable.
