No, what I mean is - tase them when they "crash" in the simulator, not when they stall.

A simulator "crash" is not nearly significant enough to their reptilian brain. Their neocortex may register it as a failure, but for the reptilian brain is just a big nothing.

Adding some physical jolt may drive the lesson deeper in their psyche, that a crash really is a bad thing.

I don't think accidents happen because pilots don't realize crashing is a bad thing, they happen because pilots do the wrong thing. You probably want pilots that have trained on dealing with lots of different failures and can do the right thing as correctly and quickly as possible, not pilots who get stressed and upset recalling the electric shocks they got during training.
