Not too sure how much the 4000 volts would help...
No, there's no stick feedback at all in the Airbus. Not only do the two sticks move totally independently of each other, but also, there is no movement associated with autopilot inputs.
In normal law, if you pitch up very steeply (you'll be limited to 25-30 degrees) the pitch will slowly reduce, even if you have full back stick in, as you approach the stall. In alternate law, the pitch down won't occur, but the stall warning will activate, but the stick will remain 'dead'.
