Since 2007 is the 10th anniversary, how about a special edition DVD release of... SPICE WORLD!
It could be a two-disc release with all the Spice Girls videos on the second disc. And
a "making of" documentary. And the interviews from the original DVD release.
Bonus points if you can get all five Spice Girls in the same room long enough to record
a commentary, though I will fully understand if the potential property damage puts you off.
... why is everyone looking at me like that?
