Don't get me wrong. The system as designed is completely reprehensible and most likely initiated a chain of events which lead to the dealths of more than 300 people. However, the point I started with is displaying the AoA in the cockpit is unlikely to have helped any of that. It's not really a safety feature except in quite specific scenarios (where the pilot is trying to extract maximum performance from an aircraft). The other point I was making is that it's unlikely that they'll fit an extra sensor or cross connect the inputs. There are few systems which receive data from both pilots and co-pilots sources.
