I've tried a couple of things from the list, and some probably won't be possible. Taking "Not as easy as it used to be" and "Part time" from the trailers probably won't work, because the sound-quality differs considerably from the movie-versions (I assume it was on-set audio), plus there's parts of the "Raiders March" playing under the first one. On the other hand, I'm not at all familiar with sound-engineering, so I don't know how clean those can be made with some filtering.

I've almost finished editing the waterfall-scene (minus the CG-additions) with audio being in 5.1 ... but as I've never edited in surround before, I'm not sure how well that worked.
