How about this:

"This guard duty is sooo boring. I want to watch the podrace going on right now."

"Whats for eats today?"
"Fish like yesterdy and the day before yesterday and the day before the day before yesterday..."

"Whats for eats?"
"You ask that every 5 minutes, and every 5 minutes I answer, fish. So in the next 5 minutes, when you ask, Ill still answer fish!"
"What kinda fish?"
"I hate you...."

Or maybe have another rebel spy as an officer who totally not subtly hints at it.

"Sir, are you a registered imperial?"
"No, sir."
"Then we will have to ask you to leave."
"No, sir."
"Why won't you leave?"
"I'm a spy."
"For who?"
"The *Revel Alliance."
"Okay, go about your business."
*Not a typo.
Just to prove a point, aka Imperial Troops/Officers are dumb.

Lol Fuff, that sounds like your every day stormie.

epic lulz thats gold fluff

You constantly typo my name a Fuff. It's Fluffy. Just though you might want to know.
"Please don't tap on the glass. The aquatic life don't like it, and they already don't like you."

"Dam, your toast is BURNT! Better get scraping."

You should have that or something like it. if you character gets in trouble at some point, which I'm sure he'll have to.

Im not sure if this is possible but you could put in some imperial recruiting posters theres some on google images

An oficer:
"Unauthorized personnel get cake if they leave.

Nearby stormie:
"That cake he told you about... It's a lie."

Imperial 1: "Great, I lost my contact lens"
Imperial 2: "We've all lost our contacts, which is why we can't hit a target 2 feet away"

I'll admit this quote probably isn't as good as everyone else's, but it's worth a shot!

Maybe if there's some 'target practice' objective...

"All Stormtroopers must be able to hit a moving target at a range of ten feet. Those who fail will be used as target practice"

"I'm sorry sir, but this is a restricted area, you'll have to go back"

"Heard rumors there might be a spy here, keep a look out for anyone suspicious"

"Need assistance sir? The Hangar holding the subs is the dome to the *directions*"

Maybe a sign on a wall saying something about the imperials. Talk to the 2 stormies near the sign and:
You:"What's with the sign?"
Stormie 1:"Well' we were asked to teach our new recruit Basic, and when he attacked, we found that CB-002's gun was full of crayons. Make use of what ya got."
RvB reference.

You are now under arrest! Stand by to be terminated.

Uh, what?

You made an insult to all the Officers and Military of the Galactic Empire. And we do not take insults carefully.

Will there be a conquest mode for these maps? i.e. not-campaign, for those of us who would just like to shoot things up instead of following a story?

I change it. It's now a reference to Episode IV
