What I'd like to see, and which would never happen, would be if they were able to go back to the original instrument tracks before they were bounced down and combined due to the two-four-and-eight track recording limitations of the time. If they could go back to the actual tape that recorded each instrument direct and do a stereo re-mix of it while George "The Fifth Beatle" Martin and Paul are still alive (though by all accounts Paul may be less than interested in doing this, so Sir George would be enough for me). Chances are they would abandon the 100% left channel, 100% right channel tendencies in the present recordings and do true, proper stereo mixes of the songs. Couple that with the added fidelity of the original instrument tracks and you'd have a near-orgasmic experience for Beatles fans.
That set I would pay $500 or more for.
Slap that on high bit rate Blu Ray a la Neil Young, and sky's the limit.

EDIT - I see I was posting on an old version of the page and didn't see Shane's post, which contains many of my sentiments.
I don't know if the original elements still exist, I'm probably pipe dreaming. I'm not sure if after they were bounced down (several tracks combined into one track so it would free up additional tracks for use) the original stems were kept and, more important somehow preserved against the ravages of time. Also I don't know if the mix notes were kept, though again, since we would want them to abandon the old style of stereo mixing, I'm not sure the mix notes are all that important.
But locating the hundreds of instrument tracks per album, in a sea of multiple takes per song, would be a daunting task. One which I'd gladly undertake for a pittance...just in case Sir George is reading...
