A cat is an aerodynamically unstable craft. An aeroplane is an aerodynamically stable craft. Yes, there are aerodynamically unstable aircraft, generally for military purposes. They are compared to throwing a dart arrow backwards. The aircraft wants to turn but the on board computers keep the plane stable.
So it is theoreticly possible to have an on board system that prevent flips on cats but the engineering cost will be on military proportions.
A good safety cockpit will probably give the most bang for the buck if engineered the right way.
