The UI is in scaleform or some other pansy wretched thing that can not be edited by RBF converting. Damnation upon it! So in short, no. Sorry. Same damn thing limits the accesories to 3 I think. (We hates it! We'll poke its eyeses out!)
It might be possible to mod in drop pods that would spawn your squads... but I think that would not work without SCAR.
