Sounds like a potential "Lion's Game" scenario.
I've been thinking an external control system for emergencies would be a good idea since Payne Stewart and his companions asphyxiated in flight, but could not be rescued until the plane crashed.
It might also be a way for someone who has gotten into real trouble in the mode of JFK, Jr. to avoid disaster.
There are also instances when the pilot is stricken ill, that such a system could save lives.
Eventually, Moeller's highway in the sky may be a necessity anyway, and all planes might need similar equipment.
