IMHO, I believe, if integration is allowed, we might see a transition of our F-16's to strike and interdiction roles and leaving the air superiority domain to J-10 and JF-17 bloc III and then J-35 whenever that comes.
That is why we might be willing to swap out the Iraqi F-16's with JF-17's. But the sticking point remains the integration of non-US munitions and various other permissions for upgrades in Turkey.
100 or so multirole fighters in PAF stock, in future, remains the shorter broad sword of the PAF arsenal with fleet maint. support and upgrades available well into the late 30's if relations permit.
