Inserting a "pilotless control system" into a previously manned fighter does nothing to improve its performance, and degrades it in many ways (i.e. situational awareness). Where unmanned systems do better is in size and weight since they don't have to carry all the gear to support a human. Although you can remove ejection seats, oxygen gear etc from a manned fighter, unmanned really needs to be designed from the ground up.
