I tried it. It was neat, but ultimately it was more suspenseful and atmospheric without it.
There is a lot more to it than just putting the music in… you also have to put the shots in the correct order and / or add the missing shots to get the proper cues.
I dunno man, the duel music syncs almost 100% perfectly with the editing, down to the scene changes. I’m pretty sure it was pulled out of the sound mix at the last minute and as such there aren’t any editing changes necessary.
I don’t think the same can be said for many other cut music cues from ESB, though - the probe droid music definitely feels off with what’s happening on screen. But the duel music doesn’t at all.
