Surely the only inputs to the stick force would be the elevator/stab "misalignment" and the dynamic pressure (q). I cannot see how AoA could make a useful contribution to the stick force calculation.
When I say "elevator/stab misalignment", I am referring to the angular difference between the stab and elevator positions. When those two are aligned, the angle is zero and the stick force is zero. Push or pull the column slightly, however, and there is then a slight misalignment - with consequent opposing stick force (of magnitude equal to the product of the angle and the dynamic pressure (q)).
Note that the stick force resists the movement of the column away from the centered (neutral) position.
This is my understanding of how it all works. I cannot see any other way that it could work.
