It'd be nice to see her in some sort of cameo, but I highly doubt that will ever happen.

Bioware have been very careful to try and separate as much as possible the 'universes' of the books and games, so that canon issues don't get involved and the player's choices don't impact on characters in the novels. We've seen some exceptions (the Anderson/Udina councillor fiasco) but for the most part Drew Karpyshyn has worked to keep them apart.

Of course it'd be possible to introduce Sanders (or Hendel, or whichever other character you want) into ME3 or DLC as a minor cameo character or quest-giver, but I can't see this happening if the player's choices can impact characters who may yet appear in future novels.
