I would be interested in how you would intend to wash out the phugoid damping term, from the alpha protect law, at low altitude, over a very short time interval, while there is a good chance that the side stick is being held fully aft, and not create even worse handling problems. Seems like it could be a fun day in the engineering sim.
You don't seem to have addressed if, at the speed available, there is any advantage in terms of manoeuvre in even attempting to increase alpha.
Your stylized CL/Alpha curve may show the relationship of various alpha limits, but in no way does it represent the A320 CL/Alpha curve, nor does show just how much usable CL was left available.
