Maybe......but a crew must know that the aircraft is stalled in order to recover from it. When the airplane is flying you......it's too late!
No offense intended but you have some serious misunderstandings about how the Airbus flt controls and warning systems operate.
The airplane was screaming STALL STALL STALL and "cricket" was chirping, which is basically the master warning, all the way to the ground. So I have no idea how they didn't know the airplane was in a stall.
Secondly the airplane was in flight control alternate law which means that the stick was giving direct commands to the control surfaces. It did exactly what the pilot asked it to do. IF the airplane would have been in flight control normal law it would have gone to max thrust and pitched the nose down automatically and overridden the pilots inputs.
Now the whole thing about one guy not knowing what the other guy is doing because both sticks don't move in conjunction with each other I 100% agree that is the most poorly designed and dangerous system I've ever had the misfortune of flying.
However in the case of the 727 and the DC-8 that both stalled and were held into a stall those guys also had full cockpit and aerodynamic indications of a stall and still held the nose up all the way to the ground. Which IMO indicates a serious training issue.
Take a look at these and tell me what happened in both cases.
This one is eerily familiar to the Air France crash.

Here is another also in a Jurassic jet.
