I would say they are acceptable if both players agree, hopefully your FO vehicle is far enough away the extra com gear is not obvious. With WW2 stuff though have to be a bit careful those ring ariels would make it pretty obvious its a command vehicle of some type quite far out. Of course if it spent say a 1/3rd of a turn 1 minute approx in view a positive ID would be on the cards or issuing of army reg specs. If 1 turn represented a few seconds the idea would have merrit.
