IMO if a radar equipped plane was allowed to show a display to all friendlies with a smaller radar circle, then why not? If it was abel to carry all that wieght in radar equipment, it wouldnt be able to carry any armament, and therefore a fairly easy target unless defended, and we all know how hard it can be to defend an unarmed goon!
It would basically only be useful for a short range where any enemy aircraft would be either in visual range or just outside of visual range. I dont see any use here for plugging radar gaps.
