So the obvious solution here is to remove either sandbags or bunker/fighting positions from USF and OKW.

Really though, I think it'd be simple enough to make bunkers as cover work just fine, just reduce the cost of the bunker's upfront manpower cost, and then add that cost to the upgraded versions of the bunker instead.
