I've always wanted a Superman series that would progress in real time, from day 1 when Kal-El's rocket landed on Earth. Really watch him progress from Super-Tot to Superboy to Superman (can you tell I'm a Silver Age fan?) Yes, it'll take 20+ years for him to reach Metropolis and the odds of something like that working is unlikely, but I can always dream. The only question is setting: Does it start in 1916 (for a 1938 debut) or whatever present day it's published? If set in the modern day, you can think of it as the preparation for the next reboot.
