Look, its not very difficult to realize that JFT will Never become a 5th Gen stealth, because this would require a complete revamp, including frame expansion, which would at least make it a Medium Class fighter, at least, not a JF-17 class one. The other more realistic option discussed to death is that there will be a limited tweaking of the system which could help reducing its radar cross section significantly. i.e. Canted Tails, Reduction of IR signature, RAM, IRST (Subsititution of Radar Sig at short range). E'm not shooting you, but pointing to the fact that this thing has been discussed to "many deaths" in this thread. If you would have gone through the thread, I am sure that you would not have any need to repeat the point.
