Medium suits can't use partial wings, only lights and PA(L)/Exos.
Even if they could, you'd be better using a Jump Booster, which only masses 125kg on a medium. By switching to a Jump Booster, you'd have 75kg unallocated, with all sorts of possibilities then available, such as increasing the ground MP to 3 and adding a Light TAG, or adding a point of armor, or adding a Firedrake or LMG.
