Except for Show Don't Tell, Superconductor and Manhattan Project all those other songs have been done by Rush since their comeback tour in 2002. I wouldn't count on any of them getting back in since they've already done them and Rush has said they wanna get as many songs documented live as possible.
Show Don't Tell is a possibility but I don't see Superconductor being played again. It's an OK tune but it would be a waste of time now.
