I wanted to make a squad that used Mara as a shooter for more than just the first round or two.

Mara Jade, Jedi (45)
Prince Xizor (40)
Han Solo, Rebel Hero (35)
Lobot (27)
Jaina Solo (25)
Talon Karrde (24)
Ugnaught Demolitionist (3)
--------------------
199 points - 7-13 activations

So if Talon can win initiative, Mara is twinning at +16 for 30 damage with Accurate Shot. Han can Mobile Attack at +15 for 30 damage. Xizor and Jaina move up to try to provide some interference and get Gambit. Once the enemy closes in on the shooters, Mara can Lightsaber Assault for 140 damage, potentially.

One alternative would be to take Corran Horn instead of Xizor--Mara would lose Accurate Shot, but Corran would be a more effective beatstick in the Gambit zone.
