If you're going to manufacture a CD, I think you need to make it a "collectible." Not just the music in a jewel box with an insert with a picture and track listings, but something special in addition. You'd have to give some thought to what that might be, since it needs to be genuine and integral to the group.
Another thing to consider is an LP/CD combo, or even an LP/CD/mp3 combo. The LP in and of itself makes the package a collectible. Also, an LP requires an LP-sized cover, which is far more attractive and alluring than a CD-sized cover. Maybe also signed by the band members?
