I was researching this topic a few weeks back for the T2030 project and came across a tentative divisional designation/reactivation list put together by something called the United States Army Center of Military History. They call it a "lineage scheme".

In descending order of reactivation/designation:

7th Infantry Division*
9th Infantry Division*
24th Infantry Division*
5th Infantry Division*
2nd Armored Division*
3rd Armored Division*
8th Infantry Division*
