Pak need to induct long range air defence system with co.plete umbrella of airdefence systems from short range to long and must have 3 different types of SAM in each category and have new jamming systems
That might be the next step.
In my personal opinion there has been a shift in Pak's strategy(in terms of weaponry) over the past decade or so. Pak's focus has shifted to somewhat more defensive than offensive. Examples include JF17/Al-Khalid. There was also recent news about acquiring the TAI 129 attack helicopter with some TOT.
Being able to produce these platforms domestically(at least in part if not completely) keeps the cost comparatively lower than importing and allows for a more robust supply chain for repairs and other such issues. These platforms have sufficient capabilities to be able to defend well and are low cost enough to make up numbers.
Of course there's the more expensive and more capable platforms in the arsenal for the offensive punch like F16(possible twin engine 5th gen like FC31?), Al-Haider program(on the way), and AH1Z attack helicopters. However I think the first goal is to be able to defend against an Indian invasion well and not be as effected by losses of aircraft/tanks as much(compared to our past wars) in a prolonged war.
If my theory is correct then we will see this happen more and more over time for various other platforms. This makes Pak less susceptible to a war of attrition and better able to defend the whole of its territory and airspace.
Keeping in view that goal of "covering all defensive needs first", I expect(in time) Pakistan will acquire(or develop?) multi-layered SAM systems. However that might be the last thing on the list bcuz a SAM system acts mostly as a defensive platform and can't double as an offensive(if needed to be used as such) platform like JF17, Al-Khalid, etc.
But eventually when this does happen it would be quite difficult for any invading force to go about their business if they were met with hundreds of tanks, attack helicopters, jets(and maybe a decent amount of submarines?) in enemy territory laced with layered SAM systems and coastal batteries, complimented by AWACS/P3C Orions/Ground based radars and jamming systems...all connected and working in sync to paint a complete picture of the battlefield.
