I would say add the hoth versions of the rebels and add some flying vehicles like a tie fighter, x-wing, Snowspeeder, arc 170, geiosnosis starfigther and the LAAT guship. that would be cool to make some space battles too. and some more empire skin options too, like refined stromtrooper look, and a shocktrooper varient with the red markings, along with a stomrtrooper commander and shadowtrooper.
