There's not much of a rebooted universe left though. The Legion ,the New Teen Titans , Johns' Titans and the JSA are all being restored to continuity this fall.
Ma and Pa Kent are like the last domino left to go full on pre flashpoint.(except for Steve Trever ,Etta Candy and Linda and Wally's kids)
Personally I'd be cool with him going back to Hawaii. It's unique, it looks cool and it's likely that it's fun for the artists to draw. A fortress within a volcano would be hella cool as well.
