First off, let me just state that I love the music in LoS, but I do indeed understand the desire for a more traditional CV feel to the music in the purely old-school sense.
Having said this, I can't believe that neither I nor anyone else has thought of and done what I'm about to suggest (as far as I know).
Considering that the majority of us on this forum are die-hard CV fans, it stands to reason that most of us have a large amount of CV music on hand. So, put this supposed "superior" CV music on your 360/PS3 HDD's, and play that music while playing the game. I'm not sure about the PS3, but at least on the 360 you can make an entire mix of all the CV music you want and just let it play continually. Problem solved.
I thought of this because LoS 'Belmont Theme' is really epic (imo), and I wanted to listen to it while fighting the last boss (was awesome). Then I figured why not just transfer over a bunch of CV music while I'm at it. Works great!
