Of course it is a point defense system, but the problem i see with intercepting cruise missiles in general is they are usually launched in swarms depending on the importance of the target which makes interception of every single missile almost impossible. That is a major threat even big powers...
Very hard to counter cruise missile in the modern world, best bet are probably aerostat with radars or AWACS. Even than, targeting them is harder given Iran's mountainous terrain and NOE flight many cruise missiles fly.
Going to need French help to code the missile in, but why would you want it? Not worth the cost nor the edge it would gain over just buying more Rafales or MiG-29s for example.
Well those are already much worse than the F-14As so no point in reverse engineering them anyway. Now something like the Block 60 would be great for Iran to reverse engineer but it will never happen.
