That would make a really nice cover image, but it's not going to happen with Roy Disney's sig on it!
But what to fill the two discs? Here's my personal run down of what they could do to bolster up material. The first disc, of course, would be devoted to SOTS and some behind the scenes material (enough exists, as seen on many bootlegs):
Radio Interviews from the 1946 Release, featuring Johnny Mercer and Walt Disney
Re-issue Radio Commercials from 1973
Original Press Kit Materials from the 1946 Release
1946 and 1986 Theatrical and Re-issue Trailers
Stills Gallery featuring Concepts, Storyboards, Publicity and Promotional Artwork
Extensive Gallery of Song Of The South Collectibles
DisneyLand’s Splash Mountain, based on Song Of The South
Zip-A-Dee-Doo-Dah: Variations on a Theme (a look at the different versions of the song over the years)
A featurette on Disney child star Bobby Driscoll, with scenes from Treasure Island, So Dear To My Heart, Peter Pan and and an excerpt from the 1950 TV show One Hour In Wonderland
Disc Two, as well as showcasing a newly created documentary, say called "Zip-A-Dee-Doo-Dah: The Making Of Song Of The South" which discusses the reasons that it has not been seen in so long, could also house other Disney hot potatoes: "The Martins And The Coys" segment, uncut from Make Mine Music, as well as the 2002 animated short "John Henry", which was released as part of the American Legends disc, but hasn't been seen uncut with front and end titles and in original ratio. This also shares similar themes and reasons for not being widely seen, so would be a good fit.
Finally, a documentary on other "touchy" subjects could be included, featuring several more scenes from politically corrected Disney films. Here, we'd see uncut scenes from Melody Time, Saludos Amigos and Fantasia.
I'd say, what with any other bits of previously self-censored material, a 2-disc set like this would be absolutely grand! Could it happen?
Maybe sooner than we might imagine:
