A couple of ideas that popped into my head seeing Spence's preview edits which might be of general use.

Using the Tatooine celebrations and altered footage from TPM to have the slaves of Tatooine throw off their shackles with Jabba now dead (meaning that from a certain point of view Anakin's childhood dream comes true) and maybe with added footage helping with a local insurrection against Imperial forces.

Using footage from different films to turn the Coruscant celebrations into an out and out riot which the stormtroopers can no longer repel because they are so outnumbered.

Now that people don't fear them they are more likely to risk death to get rid of them.

Current scenes in Cairo and Tunis may serve as an inspiration for editors (though I stress to point out I'm not trivialising the real life tragedies connected to these events).
