smilin ed you are showing your ignorance of air data systems.
Even analogue aircraft use AOA position for error correction of the air data system. So an analogue aircraft flying with 2 u/s AOA's would be in as much danger as any other aircraft.
It could affect more than just stall warning (depending on installation) and could become critical at low speed low altitude depending on the error induced.
I can't remember the exact figures but the MD11 used to cause problems in the early days during testing. If the AOA's were not all in the same position on the ground the air data readings would show huge differences between systems 1+2
