If you look at the inner most Pylon for the Drop Tank, its deep (height) enough to have a AIM-9/PL-5 class missile mount installed to the side of it, just like F-15 has. I don't think there is enough room for two with on one each side, but definitely on the outer side. Yes it will require wind-tunnel testing, modifying code etc, but it will free up the wing-tip mount for SD-10 type. This probably be the easier and faster way to add weapon station to it for the AAM mode, it will give JF-17 6 SD-10 (four on duel rack, two wing-tips ) and two PL-5s/8s/10s on inner-fuel tank pylon.
