Well, if it had gone into affect, the industrial dismantling part would have stopped more or less as OTL as the USSR would become the bigger threat and the Allied powers would likely still see a capable Germany as part fo their side a good thing.
Poland would be smaller, France would likely annex the Saar protectorate, though as for Germany proper a few different scenarios could happen.
For isntance, the one below, Denmark is awarded Sleschwig-Holstein, while Southern Germany becomes the BRD, Eastern Germany becomes the DDR and the Internatioanlized area of Western Germany becomes the NDR.
Now, as for the NDR and BRD, they could merge to form the FRG, or they may stay seperate, I don't know, but all in all if German Reunification went on schedule modern Germany would be larger.
