Just thought, I don't think it's in "Vanilla" HoI2, but maybe a idea for a "battle scenario mod"
What might happen, when the Battle for the Ardennes is a success, German forces captures allied supplies, drive them back and the allied high command decides to evacude France the second time. Then in the winter the German War Industry produces on "full war effort" and in spring a large German counter attack...
So if you're successfull in the "Battle of the Bulge", your remaining units (with their individuell strength) will chance to the eastfront, where some already existant troops will already be there, and then you try to stop the advancing red army. If successfull, you might even going farther, maybe re-conquering Italy, or trying the second attack on the Sowjet Union itself... And everything with the Battle Scenarios, not the whole map....
