I played around with your concept and came up with this:
Attack on the Jedi TempleBasically, I traded Thrawn for more firepower and kept only one 501st Legion Clone Commander for his CE.
501st Stormies shoot at +12/30 against anyone when carefully placed, add 10 damage to Force users and cunning to the mix and you should do well.
Oh and with the preferred reinforcements you get double override and plenty of mouse droids to use as shields.
