The main limitation with Hurjet is it's engine, you can't sell it to anyone outside of US allies, and there is no program or even any slight talk or hint about a domestic engine for Hurjet(at least not yet) so even if it has the possibility of selling like hot cakes, Turkey won't be able to sell it as hot cakes for the reason i mentioned.
Which is really weird, Hurjet is already finished and will become a mature program much sooner than Kaan, i wonder why they don't consider a domestic engine for it?
