Or they could get one of the NPCs to handle the turret. After all, when you've got a Mandalorian veteran like Canderous, an experienced smuggler like Jolee and HK-47, whose programming incudes enough knowledge of Sith fighters and their tactics to run freakin' combat sims, how much sense does it make to send some schmoe who doesn't know the fire button from the windscreen wipers?
I'm not sure if this would have worked in KOTOR, when messing up the turret game meant getting killed - I'd be pretty hacked off if some NPC got me vaporised - but in Sith Lords, where it looks like you'll only get boarded if you fail, it might be possible.
