A non-emitting F-7PG could fire an IR-Darter guided by AWACs or other aircraft in the formation. That would make an interesting interceptor.
I am also very interested in the close air support capability of the F-7PG. The wing design means it is far more ideal than a regular MiG-21 could ever be for such a mission. Basically, Pakistan has an area between Southern Punjab and Northern Sindh where there is a "gap" and it is expected that Indian armored forces could move towards this area with possible maneuver warfare taking place. A defensive CAS mission would not need long legs, just a good variety of munitions, a few passes in this open and inaccessible desert would leave any incoming armored formations worse for wear.
PAF has a habit of evaluating all kinds of systems, almost anything it gets in hands on. It is very hard to guess what the PAF will buy based on an evaluation.
It would be amazing if the PAF got Eurofighters with Meteor integration. That would be a killer counter to the IAF as the Eurofighter has always been the better a2a platform.
