How could the Morgenthau Plan for the future of Germany post-WWII been fully implemented, and what would be the effects on the Cold War and postwar Europe?
It was impractical, if not outright counter-productive in the face of the Cold War. If the Western Allies had continued with the deconstruction of industry in the face of the ensuing Cold War and a Soviet remilitarization of the DDR, they might have even risked that the general West German population would have become favourable of the Soviet cause because they might have seen it as salvation from the West and it's Morgenthau Plan.
2) It would have slowed down the reconstruction of Europe as a whole. Without Germany's industrial base, Europe as a whole would have recovered far slower from WWII.

Well, the Allies were restricting food shipments and international aid organizations from entering Germany until 1946, which might fall under the depopulation category.
