For maximum benefit of this, JF-17 Block III should incorporated features of frontal stealth. I do not know if that would happen, just hope that it does.
Chak yaar, It is remarkable small (smaller the f16 which is or was light weight fighter) and has even DSI, MAWS, DRFM wit huge library of ECM... Making this one stealth does not make much sense anymore. If you add weapons externally any plane loses whatever they call Low Observable... You can add paint later on or do some minor changes here and there (saw tooth's, body antenna's) but the cost are huge and you do not get that much improvement over what you already have. Just go compare F22 (a picture with F7 and JF17 is same as F7) or MKI.... I think you get the point.
