They could probably create an edit of Blond Ambition that merges Alek's footage with the remastered Nice footage if they really wanted to release the show in full, since Alek said himself that he would love to restore that. If he's able to get the source footage, then it shouldn't be too bad.
Bolded is everything we they filmed for Truth or Dare, since it's all featured in the documentary. Not sure if they filmed more than that since the original budget proposal said they'd only be taping 30% of the show. Madonna recently said they never filmed the entire thing but didn't specify how much was filmed. Assuming that's all there is, they could fill in the gaps with the Nice footage. But if we're being honest, the Dick Tracy and almost the entire Art Deco/Material Girl sections aren't that great to me. I don't feel like I'm missing a whole lot not having those.

Alternatively, I would love a Truth Or Dare Blu-ray set with bonus features like deleted scenes, ads, and other materials from the Blond Ambition/Immaculate Collection era. And of course the full length performances from the film. There's a lot of stuff they could do if they can source it all.
Deleted scenes
MTV Truth or Dare premiere
Dinner with Madonna interview with Kurt Loder
MTV VMA performance of "Vogue"
Wayne's World SNL appearance
Maybe even something new, like a roundtable with Madonna, Alek, and the dancers
