You're right, the energizer scream does sound 10 times better.
The only tricky part would be isolating the scream from the music underneath it.
It's the same problem with cutting in the dialogue exchange from the Episode II trailers:
"I've heard this lesson before" "You haven't learned anything!"
The music underneath it throws everything off.
Oh, and if anyone wants a little cut footage, check out the Xbox game:
"Don't assume just because there are two of you, that you have the advantage."
