I will like to break your post into valid responses. Certainly believe Rafale being a 4.5 Generation is well ahead, what PAF has now in its technological inventory, countering is not an easy task at all. Agility, Speed, Meteor Missiles, integration with AWACs. Rafale now is a very very dangerous aircraft in Pakistan vs India Aerial affairs ability to pull back deep into India. JF17 block 3 can hold its own depending on pilots ability, F16s too depending on pilots ability but technologically IAF has just become ahead. We could have a well integrated system, but Indians also having Mirage 2000s, Mig 21 Bisons, Su30 Mkis was an era where PAF integrated system worked well as it showed, with its SAAB 2000s/other radars and its F-16s, & JF17s, but current high technological leap-forward with Rafale while in process of netcentric warfare system integration will in reality, IAF will not take long when it becomes a very dangerous netcentric warfare unit with 6 batches in the existing netcentric warfare system integrated soon. Given PAF current system, I donot see PAF has the JF17s or F16s (its AMRAAMs were used to shoot 2 IAF jets on Feb 2019) can do much about current growing Indian Capability.
Look at this with Rafales it is big leap forward in technology and air weapons :

Above image says Rafales 36 order is almost complete with 13 soon to be completed.
Yes what we think having a diverse hardware pose a certain threat, a problem maintaining, but eventually with 4-5 platforms like USA, UK, Europe, China, Egypt is fairly common, it is not much a hassle if deployments and careful interoperability is achieved. In Certain conditions this can give a surprise edge over the adversary on the type of aircraft coming onto the attack while everyone knows PAF has JF17s,F16s and point defense F7s only. India used 4 attacking platforms to play around Pakistan by using Mirage 2000s, Mig 21 Bisons, Su 30 Mki and Mig 29s with also backhand support of its AWACS platforms. Although Pakistan decided its very own operation Swift Retort to respond in kind successfully destroying Mig 21 and Su30Mki, but it does not mean PAF had a successful defence strategy when IAF managed to come and also fire its Spider 2000 bombs at Balakot from 100kms earlier at night hours with multiple cross border entries into Karachi side, Bhalwapur/Mutlan side and then eventually Balakot making a deceiving tactic to Pakistan.
Agree once Rafale is integrated it is already a standalone deadly aircraft but will become even more deadly sharp killer when integrated with latest weapons and AWACS, and which actually now made me ask, does PAF has effective ways to counter this huge coming threat.
Loosing 2 Jf17s with 2 pilots to 1 Rafale jet. I am not sure this is how PAF thinks in tactical battles, its about success in the overall political objectives which has made PAF the most successful organization. Can 2 JF17s actually down 1 Rafale provided its ever alone?
Better start worrying big time. India's depth is a big issue, that is exactly what India is thinking in times of pulling back among hostilities, IAF can pull back deep into various positions in India, and Pakistan must need to find a way out of this. PAF can match with agile, superior technology, better trainings programmes, better efficiency and a pull back air space contract with Afghanistan and Iran in times of high hostility.
