This is an idea that would have been pursued if it was possible. While the jet fuselage, landing gear, engines etc will be very similar the problem is that the technology is very different as they use NATO standard while we have our own.
The problem will be that the technology like radars, sensors, software, EW, maybe a derated engine, missiles, bombs, instruments, towed decoy, IRST, encrypted software defined radios etc will be very different. Any technology that NATO uses will be unavailable to us as we are not part of NATO and the rules state that any technology, parts, components, sensors, weapons etc will have to be an inferior version to what NATO uses so that they can retain military superiority over any technology exported to a non NATO country.
