OH! What if an ewok spy can be matted into the foreground of the scene where the rebels first exit the shuttle tyderium. If the rebels are seen exiting an imperial ship, the ewoks would see them as enemies, the same as the imperials. R2 and 3PO would have to be matted out of that shot until the ewok spies left, of course.

Cool. Just like a shadowy figure in the bushes that watches them and makes those Wicket growling noises as he watches them. Could add some early suspense for the audience too. The ewoks would certainly know the Imperial equipment by then too. Shuttles, Walkers, AT-STs would all be regarded as containing the enemy.

I think it would be good just for comedy factor, but plot wise - the Ewoks try to cook Han Solo & Luke and also tie up poor Artoo... I think that already suggests they dont like them.
