CAC in Australia later being brought in for the assembly of McDonnell kits,
which then transitioned into the licensed manufacture of some assemblies and the service support
contracts. The CAC assembled aircraft were originally only for the RAAF, but later they received
a contract to supply aircraft for the Philippine Air Force and Taiwan.
Hmmm...I'm liking your thinking. Given the F-101 had the long range it might very well have found favour. If one could find a way to deal with timings, in RAAF service it could very well have supplemented and then replaced the CAC Sabre and even the EE Canberra and adopting the roles of long range fighter/interceptor, recon and even strike aircraft with both B and C and even RF variants. An engine change as suggested, especially if it followed later real world developments of the Olympus (though possibly brought forward), is also interesting. Could make an interesting alternative to the F-4 for many
