Just thought I'd give an update:
Got him to 7*, first try. Was easier than I thought it would be.
EP lead g9, Vader g9, Tarkin g9, TFP g9, Stormtrooper g8 - all in the mid 70s for level. Abilities were almost all at 7 (omega on EP and Vader basics), except ST with abilities at 5-6.
Took out Han, then Leia, then Luke, then R2, then tanks (kept tanks shocked when I could, to prevent taunt).
Lost TFP right away, Stormtrooper later when he taunted, and that was it.
Didn't even have to move my mods around.
Best of luck to everyone else =)
