Hmm. I agree on the Ash/Kaidan DLC, because one of the two is guaranteed to be alive, and it would make for an interesting reunion.

But Thane would be problematic (indeed, any ME2 squadmate would be...). Strictly speaking, canonically, he could be either alive or dead after the conclusion of ME2 - and within many players' save games, he most definitely is. It makes little business sense for Bioware to create a DLC pack around a character that may not even be alive in some (or many, we have no idea) players' games. For this reason I don't think we'll be seeing much post-game DLC content for ME2 squadmates for the forseeable future.
