NOTE: What I suggest below does NOT meet the criterion of 25 million dollars in the thread title, but I hope nobody minds me discussing this here.
It just struck me that the main limitation facing JF-17 is the amount of weight it can pull. And the main limitation in removing this deficiency is availability of engines. Well, what if we design a two engine 'big brother' version of JF-17 using the existing RD-93? My main question is, would that be viable?
From the OP, it supports a max weight of 12474kg. Since the empty weight of the aircraft is 6411kg, and max weight is 12474kg, that makes the payload equal to 6063kg. If worse comes to worse and a twin engine design could increase the payload by only 50%, that would still be 9094.5kg. Now, in the world of twin engine fighter jets that would be laughable. The Su-35 supports a payload of 16100kg calculated based on specs found here:

BUT, if it is fast, agile, and nimble, we now have a platform where we can fit the AESA, IRST, and other goodies without problems. Of course this is under the assumption that our twin engine design would be so bloated that the payload gain sits at a mere 50%.
