The "good guys" would be Jack as Han Solo, because he is the de facto leader of the rebel squad fleeing Darth Vader (Ben).
Kate would be Leia, because she is the lead female character.
Locke would be Chewbacca because of the hair.
Or lack thereof. Besides, Locke played second chair to Jack for most of the series.
Sawyer could be Luke, but the actual romance angle with Kate is beyond PG-13. But as the "golden" street smart guy who seems to get into and out of trouble easily, C-3PO.
Likewise, the banter allows Hurley to be R2-D2, the character that no one seems threatened by.
At least in LOST WARS, you know who you were fighting (Widmore) the evil empire. And the story would be fairly linear - - - attack, counterattack, capture, escape, victory.
