What Elseworlds did you want to see published? I have a list (but I'll give you my top 5):
1)Elseworld's Finest:Instead of Supergirl in the JSA you had a young Kal-El discovered by the Golden Age Hawkman,Flash, and Green Lantern.
2)Captain Marvel Jr. and the Legion of Superheroes
3) The Chronicles of Jon Kent(Kingdom)
4)Worlds Finest jr: Jason Todd & Superboy Prime if he went back to Earth instead of staying With Alex and Superman of Earth 2.
5)X-Patrol:A whole mini series with them stranded in the DCU.
