I see that Colombelles map is a bit bigger than actually used in 4vs4 setup.
What I suggest is simple: Make a Colombelles 10vs10 map that is increasing the map size by 10%, which should include all the areas you see in the 4vs4 setting which are currently "grey" and unusable but already modelled.
That way the game would be perfect with a little bigger map (rougly a 5vs5 or 6vs6 map size) but not too big for people who like Steel Division Roleplay ( you are ground, u are arty, u are air and so on).
