You are conflating the concepts of aerodynamic stability and linear feel response. MCAS was created to address the second, not the first, issue.
No, the aircraft pitches up in high AoA and high G manuvers. The aircraft tends to stall at low speed. You dont try to modify the wings for stick feel.
MCAS pitches the nose down 2.5 degrees in low speed stall, that is not to make the stick feel the same...it is anti-stall.
stick feel is the result, not the cause.
