Yes, if it's possible, it's certainly worth at least trying rescuing what's left. It's very possible however that the rescue operation can simply be too complicated and too time demanding for the people involved, and that at the end the amount of the rescued data is too small. Apparently what is missing is "all the organization and notes" of the scanned photos.
