Coming back to CivIII after some time I must first give you thumbs up for some brilliant new units (all kinds, not only aircrafts)
Then be bold enough to ask for something. In your Air Force you got almost every possible nation covered, and even for modern conflicts we have had and have after WW2.
So will you think on some aircrafts froom Pakistani Air Force ??
Like JF-17 (similar to F-16 I think)
The different Mirages they have had in the past and still have
They of course got F-16 too
Older like Hawker Fury, Supermarine Attacker, J-6 (Mig-19), F-104,F-86
Most cases just using other nations for these, but I think the newer JF-17 could be a cool addition.
