That is what the Jinnah class is. Its a stretched and fattened Babur class, which is a stretched and fattened Ada class.
No wheel is being reinvented, the main changes were a revised superstructure and potentially bow (from memory, i cant be bothered to dig up the photo tbh), none of this was significant in the sense that it would balloon costs, the weapons fit is marginally improved, im expecting them to go and push for a Turkish suite of sensors instead as they mature and enter production. Primarily that domestic air search AESA they had been working on- i forgot its name, but it seems like a natural progression on from the SMART-S MK2 into a more higher-end solution, whereas the MK2 is a more cost/capability balance, making compromises in one place to give benefits in another.
Aside from that, all the model really indicates is that there was an emphasis on RCS reduction, inclusion of ASROC, while also adding another 4 cells for CAMM-ER.
While Turkish missiles could be seen onboard the class, I'm skeptical for now, it would be a costly venture, the current setup, once again, is a great balance between cost/capability, VLS is expensive, very expensive, a 12 Cell MK41 setup costs $60m USD. If we were to include this on the Jinnah Class or Babur Class, it would have been even more expensive as MK41 needs to be adapted for CAMM, for this, you need an ExLS module, which sort of is an adapter, Sylver would be even pricier and the Turkish option even more expensive than the former. Also, just remember, MK41 is $60m with over 14,000 cells in service, a number which will continue to grow rapidly, it would simply be too costly to introduce a 'proper' VLS across the board, however, it does make sense for a certain type of ship, a more high end, more survivable, flag ship class, a large AAW ship to provide a defensive umbrella. But then, we need to analyse where we stop, because those missiles are not cheap either lol, SM6 costs $6m+ a shot, SM3, $35M+ a shot, and once again, these are missiles that are able to exploit those massive economies of scale.
Why would you want this, aside from missile count, the J/B class are both on par, if not superior with their significantly more modern weapons and sensors suite. The 054A is an excellent fleet builder/backbone, as the PLAN starts to decommission them, we should be picking them up.
