I think what you are trying to describe is called a "yaw damper". The purpose of this is to dampen out accummulated yaw energy that can result in a growing oscillation that will make your passengers sick (maybe even break/crash the aircraft). AFAIK we are only talking about swept wing aircraft (jets), but I could easily be wrong on that. Basically, I think you are right on how it should work, but you might want to find out how it works in the real world before deciding on an approach. It would be nice to have that feature added to the autopilot code. Usually it is activated on the ground and then turned off only to keep it from screwing up any kick-out on landing. The activating/deactivating could be handled manually or by an FMC module.
