D-V have done a couple of titles from the U/A catalog, Donald Byrd's
Black Byrd and
Street Lady. These are obviously Blue Note titles but the Blue Note catalog was under the control of U/A at the time, and has since been absorbed into UMG.
I did a thread a few years back that was a history of all the U/A (and related labels) releases which includes a full discography of both released and announced-but-never-released titles for anyone interested:

I think if the U/A catalog was under the control of Sony you'd probably see D-V tackle some of the easy listening titles like Ferrante & Teicher, but licensing from UMG is slow and more complicated so they've chosen to focus on titles with broader appeal, like the two Donald Byrd albums, and more recently the Bachman-Turner Overdrive two-fer.
Of the titles that remain, for me the real prizes would be Lou Donaldson's
Sassy Soul Strut (the third and final Blue Note quad), the two Bobby Womack titles (legendary, chart-topping albums with nice mixes), Traffic's
John Barleycorn Must Die (if a quad mix exists), the soundtrack for
Live and Let Die (for the title track alone), and maybe the Buddy Rich
Greatest Hits album, even though the quad mix isn't super discrete, because there isn't much big band music in quad. Paul Anka's
The Painter would also make an interesting release, if a discrete quad master exists (it was a single-inventory QS LP release) given that it dates from right at the end of the quad era, and Anka is right in D-V's wheelhouse, style and genre-wise.
The War titles (
Deliver the Word, The World is a Ghetto, Live Vol. 1 & 2) would make great candidates too, but sadly the rights to those titles belong to their former manager, and he's taken them to Warner Music in recent years so they're not available to D-V.
That Ventures
Only Hits double album is misleading too - it's not a greatest hits album, it's new recordings done by a group of mostly studio musicians (and not the original band) and for me, of minimal interest as a result, especially if you weigh it up against the other stuff I've listed above.
