I couldn't tell you that, because I didn't try. I worked with trackes, noise-reducted in different frequencies using the original score as noise profile.

Today I returned to this problem, using the Rear Surround track as noise profile, and despite what seemed, results were worse.

Anyway, I made a masked version of the dialogue back then, using random music (It was anakin vs obiwan theme i believe) and some of the artifacts got slightly camouflated.

I don't have means or an account to upload it, so it's up to eric

What are you using to apply noise reduction? Gating settings should exist in the noise reduction interface, since part of using noise reduction is determining and adjusting the noise gate. It's location, strength or weakness of passing in and out of it, etc. I know Audition and other stuff I use has those advanced settings.

If you created the noise profile, it created it at a single volume level for each frequency of noise. You can adjust those to the best levels (reducing the music enough but not cutting the dialogue) and adjust the settings of the noise gate to make it sound natural especially since you'll need a certain level of gating.
