I don't fully understand what you try say will be the problem.
However, like you say they will most likely place a Sungur (around 10kg) on each wing for initial weight balance but similar unbalance problems already occurs when they use just one MAM-L (22kg) so they must have 2 Sungur on one wing already covered. Keep in mind that Sungur (=Stinger) is man-portable so they are very light.
Concerning sensor pack, they might add a small AESA radar similar to what the Polish do to their TB2 for some applications but I think they will primarily use IIR/optical cameras (tailbom or FLIR) for the TB2/Sungur combo due to the very limited range of Sungur.
When fired from TB2 the range would increase significantly, no? I am thinking that the release altitude, release speed etc. will greatly extend the range.
