Been a while since we've done a fun hypothetical like this.
Let's say there's a contest and the winner get to help create the very final Club Infinite Earths line. The key word being "help" so you're trying to appease more than just yourself, otherwise my own list would just be Batman Beyond and New Gods characters (which of course I did slip in).
So a single list of 12 figures in no particular order, 1 exclusive figure, and 1 oversized figure. No alternates, no "if I could make two sets". This is to be THE last line. For my own I'm sure there were a few team building characters still needed that I didn't list, so I'm not being cruel in my exclusion. If this were real I definately would've reviewed that all better 
My list:
1. Superman Beyond
2. Captain Comet
3. Time Drake Robin (a proper one, finally)
4. Impulse
5. Spellbinder
6. Sun Boy
7. Manhunter (Mark Shaw)
8. Static
9. Hush
10. Emerald Empress
11. Count Vertigo
12. Infinity-Man
Oversized: Warhawk (edit) w/ tiny Micron
Exclusive: Granny Goodness w/ Hound
