Firstly, this is the biggest failure of IAF that now they are a rocket force only. The primary role and foremost aim of any air force is air superiority through aerial engagements and if they stay away at 200 km, they have accept PAF's aerial dominance.
Secondly, as I mentioned earlier, they have 40 Brahmos capable Su-30 only. The serviceability rate was less than 70% but even I give them better odds, they can't pitch more than 30 aircraft. With number for Rafale, maximum possible launched cruise missiles will be 60.
Now, PAF has shown the capability of soft and hard kill for all vectors, though obviously it can never be 100% as we have seen in case of Israel too. With more SHORADS and better EW, let's say it is 80%. (though it will be better as PAF has already identified the loopholes)
So that means 48 will be intercepted and 12 will hit their target which is not enough for any strategic level damage.
Thirdly, when I will go for my attack in response, Indian aircraft have to stay away and they are only banking on SAM systems. By knocking them out like S-400 mission on 10th, whole India is vulnerable till 200 km from IB.
