I have no definite answer on "should we have an AoA meter in every liner's cockpit ?"
I don't think "just" adding an AoA meter is a good idea. AF447's crew apparently didn't react on instrumentations they should have known/been trained for (namely: stall warning)...
AoA meter + associated training: why not. I agree that this training is simple.
AoA meter alone: not useful, potentially dangerous.
However:

Huh? How is that?
Stall warning logic is : ring if AoA > limit.
Then a false stall warning implies a false AoA measure IMO.
And a false AoA measure gives a false AoA reading on the AoA meter.
Same source = you cannot cross check.
