This suggestion require a lot of work for mapmakers - Propper Tactical map (iow minimap) images.
For example i took maps from Map Making Contest 2016 (
https://www.coh2.org/topic/56719/winners-annoucement)
At the moment exist 4 (2014 and 2015 variants have a lot of common) varitions os stylization of minimaps:
1. Like in 2013 (Bombarded Refinery)

2. Like in 2014 (Westwall)

3. Like in 2015 (Rüstungswerke Essen)

4. Photorealistic minimap (No one has made minimap like this, but it looks like Road to Kharkov, Minsk Pocket, or Crossroad minimap)

5. MonolithicBacon minimap (Caen)

It will be perfect to update minimaps for all maps in the game and bring them to one common style (which also will be informative and easy to use)
