FYI it looks like the Israelis are offering the Kfir NG with a 'zero-timed' airframe, AESA radar, GE F414 turbofan engine, and -- depending on end-user requirements -- new-build airframes.
With the current Kfir Block 60 that the FAC operates featuring a 'zero-timed' airframe, system, sensor, avionics (comparable with the F-16 Block 52), and weapon enhancements, the Kfir NG adds a more powerful General Electric (GE) F414 engine (as already powers the Boeing F/A-18E/F Super Hornet and Saab Gripen E/F) in place of the outdated GE J79; an enhanced active electronically scanned array (AESA) radar; improvements to the datalinks; and upgraded avionics. Another feature that is still in development is a redesigned aft-fuselage that will increase the aircraft fuel capacity. According to Melamed, this should double the Kfir's endurance.
The Kfir NG could be based on remanufactured FAC airframes, surplus Israeli Air Force airframes, or could even be new-build depending on the requirements. Melamed declined to put a timeline on the Colombian offer.
The idea of re-manufacturing and upgrading the Mirage 3/5s is seeming increasingly tenable, but this can't be an internal PAF or PAC project. With the JF-17 and Project Azm, there are too few resources available. Rather, the PAF ought to look at external contractors to carry out the work.
If Denel Aeronautics still has the Cheetah's jigs, then I think this is all doable, though it'll require breaking down whatever mental or planning blocks preventing this from being an option. In fact, given the stakes (potentially a new-build bird with 4+ gen capabilities), they can move slow and start with a pilot project (3-5 planes).
I, for one, fully support the idea of bringing new life into the Mirages if it means gaining 3~5 squadrons of dedicated deep-strike, anti-shipping and strategic/nuclear attack assets.
