Have you considered operative or sniper? They both seem cooler to me. Using a sniper rifle for long range DPS as compared to 2 pistols. Makes more sense.
And the operative attacks with a knife, along with a blaster rifle instead of a silly little pistol. Both of the imperial agents get little robot drones to help attack/defend, which is more 'Star Warsy' I think.
The scoundrel has a pistol but doesn't ever have the need to use it...Besides to pistol whip people. I love shotguns, but I think it is kind of silly you pull out a shotgun with your left hand and use it one handed, with the useless pistol always in your right hand. If the scoundrel only had a shotgun even for normal attacks, would be much better.
Overall the smuggler seems kind of silly and zany and doesn't really fit into the Star Wars universe, IMO.
