The problem with that is everyone's reaction to it. Chewie and Han don't think anything of a dead animal on a stick, but Luke senses a trap. A stormtrooper helmet on a stick with the head still inside it? Definate trap, and might even freak Han out a bit. Changing Han's line from "It's just a dead animal" to "It's just a stormtrooper head" is either extremely hilarious or extremely badass.

You could remove the line and speed up the sequence so Chewie reaches for it almost out of instinct, springing the trap without the heroes pondering what it means, keeping only Luke's warning.

Leaving in the "thinking with your stomach" line is either off or very on, we know Chewie isn't a Vegetarian from the theatrical cut and there are no Wookiee Stormtroopers so how is eating a dead human any different from eating a dead animal?

If the line is taken out or not we know Ewoks will eat humans (because they try to eat our heroes later) but now they are already pulling the heads off Stormtroopers and using them to bait traps, which adds to the surprise when we see what they are like.

But I'd keep the flesh in (the saga has arms and heads coming off all over the place so why not have a bit of neck gore?)
