Well, IMO there's a difference between stuff that was around during the Silver Age, and stuff that is imbued with distinctly Silver Age ideas. By your logic, bringing back Jimmy Olsen or Dick Grayson or Kryptonite or anyone or anything else that existed in the Silver Age would also constitute "bringing back the Silver Age", which isn't really what I meant. But hey — I can tell we're not going to agree on anything, so let's just agree to disagree. I always like to say comics are nothing if not very broad in their scope of ideas.
