Here's a small mod I made to replace the flags on the unit counters with the roundels that the game uses in parts of the ledger. I figured we already have enough rectangles on the map; a few circles add some visual variety. Plus, the roundel for the Confederacy is the famous battle flag, which I think better fits military units anyway.
One side effect that the roundel is also used on decision markers, which I also like.
There are two versions, round and oval. The round version may be a bit crisper but the oval version fits better on the counter (doesn't impinge on the unit stat bars quite so much).
Round version:

Oval version:

The files for both versions are attached zip file. Rename the version of your choice (by removing the _Round or _Oval suffix) and copy into the Civil War II\CW2\Graphics\Factions\Counter_OnMap folder.
