Just a reminder that since DC Comics no longer owns the rights or license to publish stories about Peter Cannon aka Thunderbolt (that would be Pete Morisi himself, or actually his family, since Morisi has since died), in fact, no, DC currently can't do anything with Peter Cannon. That would currently be Dynamite Press. If/when that license expires, and if the Morisi family chooses not to renew it with Dynamite, then maybe DC might want to renew that license, but they still wouldn't own the character like they currently do Captain Atom, Nightshade, Blue Beetle, etc.
