In this interview around minute 23, Mark Hamill says Han's line "Great kid, now don't get cocky". You could use it to switch the roles of Luke and Han in the scene and make Han the rookie.

Earlier in the interview around minute 18, there's Carry Fisher delivering a funnily awkward version of the "foul stench" line. And just before that, Mark is saying the original "foul stench" line, maybe you could use that when he enters the Falcon or the cantina.

Btw, make Leia recognize everyone by their foul stench.
