Nice idea, but I don't think it would work. Friendlies show up as green dots on your map, so they'd know it was an enemy by the lack of a green dot even before it is in icon range.
Granted, they have a better shot at not seeing it until the icon pops, much better chance of that.
Honestly, I think the inability to bail out of an undamaged aircraft would be the best way to go. If you have something you need to do suddenly, such as a squad op, auger it.
