The pictures showed on the first page were 054A+ (batch 2), not the basic 054 (batch 0), which were trial/transition platforms - apart from the displacements - are no better than the F-22P pakistan navy already received; nor they are 054As (batch 1) which had no inward-sloped upper portion of the bow. As many people mentioned before, there was no point of getting the basic version of 054, that would be waste of money.
I do not see much political/military/copyright obstacles to get the series production version of 054A+ for pakistan navy. Only problems will be financial and workload related, as it is going to cost at least $250-300 Milllion per ship even with uttermost discount, pakistan navy just don't have that kind of budget located for decent numbers (4~6+?) of ships this class (4000 tonnes+), in order to form a capable air defense network on the open seas.
Plus, all Chinese naval shipyards/factories capable of (which aren't many) producing 054A+ are fully geared to produce enough new FFGs to replace PLAN's aging 053H/053H1 (Jianghu-I & Jianghu-II) fleet, dated back in late 70s & early 80s, that task alone will be at least 15 frigates in the next 5~8 years, then if counting the support ships for the carrier groups, not to mention the carriers themselves. It will be very tight schedule/deadlines to meet for producing extra 054As.
I wish China could have more shipyards along the coastlines, and to raise the technical/quality control standards for those shipyards based at inland waterways (now the quality standards are low when compared with Shanghai/Guangzhou shipyards), so that the modular construction of building future combat ships can be fully utilised (e.g. build different section/portions at different inland factories, then transport and assemble them at the shipyard on the coast to reduce turn-around time.)
