Ok so a buddy of mine came up with some of this so partial credit goes to Ryals who I'm not sure is on here or not...

Blizzard Scout 1
AT-ST
Thrawn
Jagged Fel
Imp pilot x2
Mas
Lobot
Ugi

Lobot bring in: Wicket and ewok x4

so anyway you run Blizzard one out and use him to attack someone so you get flanking support then swap in the other chicken walker and use the pilots to combine fire on his two attacks also try and get wicket up there to do -8 defense on people. and you can always bring Tharwn forward to negate force powers. you can also use one of the pilots to repair the wlkers and use Fel to attack smaller pieces

It seems like a valid way to get those 40 damage attacks from the AT-ST to actually hit something other than the broad side of a Barn. -8 AC really helps you to hit even the most pesky of opponents.
