In my opinion, only if we could do so in 5 years, may be there is an option, the PAF should move ahead with some semi stealth off-the shelf platform for 4.5++ tier and then can progress with Azm. Something like FC-31/J-35 in current setup having limited internal load with option to external load-out yet with lowest RCS, stealth shaped coated fighter jet flying with almost the existing 5th Gen configuration. Why to struggle for something EFT etc when such platform can serve more than one purpose... we have a stealth as well as a 4.5++ or I may call it 4.95 gen platform in multi-role capability. With internal loadout, it is a stealth with limited fire while with external loadout, we have a advance yet almost close to 5th gen fighter jet which in the end, is going to support true Azm.
@Bilal Khan (Quwa) any thoughts....
@SQ8 can't we progress in this setup instead of us internet boys dreaming for EFT or whatever? FC-31 can do many things against single invoice.
