Brochuritis is deadly for our nascent industry- let's crawl, walk, run in that order.
First focus should be on frontal VLO characteristics. Second tranche of effort on lowering per unit cost (local engines, missiles and other components if cheaper from abroad), maintenance cost and flying cost per hour. Third wave of development to look at sheilding engine exhaust for rearward stealth. 360degree LO is more important than FBO. Star wars (lasers) weapons next.
Also is FBO a revolutionary capability? I think it will only improve control sensitivity over current FBW making the plane more nimble- which is a good to have, but does nothing for stealth the primary aim. 5th gen isn't expected to be very agile with no canards etc so what aim does FBO achieve? Probably a better fit on Mk2.
