One option that several groups have used has been to use the SPI Central Front Series for movement of WP regiments and NATO battalions, and then fight out the interesting battles with minis. This is great for giving context to the battles fought out with minis since they will have an effect on the campaign…
The scale of the CFS series is 4km per hex which just happens to be a narrow attack frontage of a WarPac regiment or a NATO battalion in defense.
Another great aspect of this approach is that each game covered a different sector of the front.
1) Fifth Corps- covered the US/German area around Fulda and Kassel (IIRC)
2) Hof Gap- covered to the East of 5th corps (the US VII corps sector)
3) BAOR- covered the main British sector from the Hartz mountains to Hannover.
4) North German Plain- covered the Hamburg area and Bremerhaven (which was the main reinforcement port).
The games have the initial dispositions which enable you to fight the initial covering force battles up near the border and then for the 1st several days of fighting with the forces in the area.
Just a recommendation on what others have done…
