Yes, and with a great deal of success. In the "Truce at Bakura Sourcebook" we learn that shortly after destroying the Death Star, Han and the Endor Strike team went on a vital mission against the Star Destroyer 'The Accuser'.
Dressed in a General's uniform and with a squad of disguised rebels he ordered the evacuation of the ship's original crew and took control of the vessel.
Ackbar: Preposterous. Surely you are exaggerating,
Page: No,sir. After all, we did have the proper
Imperial clearance - the code that allowed us
through the shield perimeter at Endor - and
General Solo was quite convincing when he
called the Accuser's captain claiming we had just
escaped from the Death Star. They certainly fell
for it; they actually used their own docking
tractor beams to bring us in.
Mothma: They brought you in?
Page: (Smiles slyly.) Yes ma'am. You could
say they invited us aboard.
Ackbar: And how did you eliminate the crew?
Page: Er, General Solo actually managed it.
Mothma: Of course he did.
Page: Once we took the bridge ... and, I swear
all we did was just walk in ... he uh, relieved the
Ackbar: Let me see if I've understood you
correctly, Lieutenant. General Solo - posing as
a stormtrooper - boarded an Imperial Star
Destroyer, marched you and your group to the
bridge and assumed command?
Page: No, sir. General Solo was wearing an
Imperial general's uniform, not stormtrooper
Mothma: (Chuckles softly.) A general. Naturally.
Solo: Hey, it fit, that's all!
Ackbar: And how did you and your team
manage to eliminate the Accuser's crew?
Page: General Solo convinced them to leave.
Mothma: convinced them ...
Ackbar: to leave ...
Page: Er, well, he rendered the Star
Destroyer's captain unconscious while my
people secured the rest ofthe bridge crew. Then
the General activated the ship-wide hull breach
alarm and ordered the crew to, er ...
Ackbar: To abandon ship.
Mothma: (Shakes head.) Amazing.
Solo: Oh, knock it off. It worked.
