A box set for spies and infiltrators, containing HWK-290 and Lambda
HWK's losing the turret and target lock, gaining bomb and evade, possibly +1 attack
Garindan (that's the long snoot spy in Mos Eisly in ANH. No ship known in Wookieepedia)
At the beginning of the combat phase, you may perform a 1 straight maneuver backwards.
At the beginning of the combat phase you may choose one enemy ship at range 1. That ship's PS is lowered by 1 (minimum of 0)
At the beginning of the end phase, if you have no stress tokens, you may set your maneuver dial and execute that maneuver
And the rebels would be something like:
(Lambda's gaining turret, losing cannon)
Your action bar gains the evade action
After you have declared the target of your attack, you may discard one shield token to roll one extra attack die when using your primary weapon.
Of course, this is rough and off the top of my head, but I would buy this box in an instant. .
