Much like a customized desktop rather than branded desktop, we can customize our all fighter jets with best possible goodies available on market to make them lethal and it can be done to mirages, F-7 PGs etc if it costs less as a stop gap till JF 17 develops into something at par with gripen, J 10c etc.
I don't know why Pakistanis don't invest in university students. Bring the brilliant minds in universities under supervision of competent scientist of say Krl, awc, PAC, HMC etc. Assign them task, give them technical support, equipment etc, guidance, funds, salaries at their very own universities with a promise of stake in financial benefits and then encourage them to make things happen. You are going to get a lot achieved in no time. Believe me. Regards.
