After the Death Star blows up and Leia tells Han that Luke is her brother, and then Han turns his head, you could have Leia turn his head back multiple times and fill it with all kinds of dialogue. It would be funny if you had them break up (perhaps you could have her say she likes Lando instead--or something completely ridiculous like C-3PO or R2-D2) and end the scene with a shocked Han looking away and skip the kiss, etc.

The repetition part has been done before, but there's still a lot you could do with that scene.
