I was actually thinking of the Sandtrooper scene, but those are interesting points as well.
The only difference between the OOT and DE-ANH in the Sandtrooper scene is that the Dewback roars, isn't it? Or were you referring to the Ronto right before the ID scene? Yes, I'd replace that in a heartbeat - but only if it's a good match for the 2004/6 DVDs.
