Thanks for the comments!

The footage comes from a 4:3 version of Battle for Endor…
Is there a widescreen source? It would blend much better.

There are many ways to integrate this into Jedi like adding some armed guards and catapults on the background somewhere. That would show that the Ewoks can fight and our friends are in some danger after being captured.

As for the battle, I see the Ewoks creating the diversion as normal, then leading the Stormtroopers into an ambush.
Makes them seem clever, by hiding their weapons and true strength.

I’ll try to put together the cannon video.
As SilverWook mentioned, perhaps we need to see the crashed ship for it to work.
