I'd go with a DOUBLE LP, an idea they toyed with originally. Here are the tracks to go on the album.
All the tracks on the issued album, PLUS ...
Only A Northern Song (was to go on the album, until George surfaced with Within You)
All Together Now
It's All Too Much
Baby You're A Rich Man
You Know My Name (imo, this fits right into the Pepper groove)
If you use the full eight-minute version of Too Much, and a full length You Know My Name, this is another album's worth of material. All songs were recorded first during Pepper sessions, or straight after.
Just think what a mind-blower of an album THAT would be. Choose your own running order.
