That's the plan. I checked through some of Jedi yesterday and found that for the most part, like Empire, the bass levels from the SE are pretty good already. But there are definitely some that are excessive and need to be reduced in order to sound like they belong there. I aim to have this done soon--it's just a matter of being able to listen to it at full blast and figuring out how to set the levels, then making another test file and listening again. Trial and error combined with creative judgement.
The Empire and Jedi LFE tracks come from the 2004 dvd's, but that's okay because they are pretty much identical to the 1997 versions, and at 448k instead of 384. For Star Wars, about 65% is from the '97 mix and about 30% from the '04, with the remaining 5% an amplification of the existing bass in the '93 stereo.
