A fin wouldn't cure an aft shift in CoP, it'd make it worse.

If not perfectly symmetrical to eliminate "lift", a vertical tail surface would add a permanent resultant sideways force working on the vehicle.

A fin also adds to the frontal area, and thus to the aerodynamic drag, the reduction of which is why the tail extension was built in the first place.
