The F-16 uses a trick to increase its hardpoint carriage weight. It lowers the aircraft's G-limit to around 2Gs in order to carry heavier fuel tanks: Once the external fuel tanks are emptied or dropped, the aircraft regains its full G capability. I've been wondering if the same is being done for the Tejas to increase its external fuel tank size on long range missions. It would be easier to do due to the digital fly by wire. Then there is the option of making a larger semi-conformal tank for the centerline hardpoint.
