In terms of 'epics', I don't think Seventh Son and Rime would be played on the same tour. AtG would be shelved as well and I think if any Somewhere in Time song would get carried over from The Future Past, it'd be Wasted Years (or Stranger or HCW.)
Loneliness would be an interesting addition, but that's another classic 'easier to whistle than sing' song for Bruce.
Ι mean, if you look at the last 3-4 tours, all of them have more than 2 epics in the setlist.
Future Past: Death of the Celts, Alexander, Hell on Earth and almost all the songs are 6+ mins long ( except Stranger, Wasted Years and DOFP)
Legacy pt2: Senjutsu, SOTC, Clansman + Hallowed and some other 6+ mins songs
Legacy pt1: Clansman, SOTC, FTGGOG + the same
BOS: The Red and the Black, TBOS, Powerslave, If Eternity...
They like lengthy songs nowadays and the 9 first albums haven't that many of them. So Seventh Son + Rime is a possibility alongside Phantom, Fear and Hallowed, because all the other songs will be shorter and some of them will be 3-4mins long.
Loneliness is indeed very difficult for Bruce, Tame also.
