Bro bro J-31 is the Chinese project, they have better resource/$$$$ than us, and Chinese has all landscape you refer to test the avionics of J-31 and as for WS-19 is still in development and if somehow Pakistan gets some WS-19 it need a Chinese help to fit MIG-29 as well as maintenance logistic, think about it, you're overestimating the Pakistan's military industries
@FuturePAF
ok ok, I give. Then we should just wait till our pilots go to China to test out the J-31 and give feedback so the design is refined per PAF specifications. Even if the PAF doesn't choose this design in the long run, as a potential design the PAF may purchase down the line, PAF should send pilots to evaluate the design and give feedback, so the SAC team can take PAF requirements into consideration when coming up with the final design.
If this is the case, Why can't this be happening now, and China can start cranking out the Planes we need in a couple years. The current J-31v2 design look advanced enough,

... and we are flying the JF-17 with Rd-93 Engines hoping for better engines to come along down the line. Why not commit to the J-31 program today. I don't see why a Block I J-31 with sidebays, and the electronics from the J-20 couldn't be flown this year, with initial operational production started in only a few years.

It seems a better option then the J-10CE, which would also take years to build and train the PAF pilots to fly. Only the need to replace the hundreds of mirages and F-7s ASAP could require the PAF to buy J-10s now, and buy the J-31 in a few years.

BTW, As a priority program the J-20s development was been as quick as possible, but the J-31 can do it faster, as the J-20 has lead the way. The J-20's first flight was January 2011, and by the end of 2015 the last prototype had flown with initial production starting thereafter. LRIP aircraft started in 2016, flew in the 2016 Zhuhai Airshow, and entered PLAAF service at the end of 2016. By March 2019, at least 3 J-20s are operationally deployed at a base facing Japan and Taiwan.
The J-31 first flew in October 2012, with the second prototype flying in December 2016. If the PLAAF and/or the PLANAF have signed onto the J-31, a production model may fly this year, with operational capability achieved by 2022 (where the J-20 reached in 2016).
