#43 Superboy and the Legion of Super-Heroes. A 48-page book with one main, 22-page adventure featuring Superboy and a rotating group of 3-7 Legionnaires tackling cosmic menaces through time and space (but mostly the Legion’s own 30th century), and then two 13-page solo adventures of Legionnaires (any ones who debuted by 1979). Because Superboy/Superman II is time-traveling to work with the Legion, he can show up at any age out of order, but the Legionaires are from 2979 ($3.75 book).

Once each title starts, it will progress in real time from month to month. Characters will grow, age, and rotate out of the spotlight. Lastly, imagine these titles being created, not by unknown and untested writers, but by true masters like Jerry Ordway, John Byrne, Walt Simonson, Roger Stern, and David Micheline. Unpopular back-up stories (or just to beat a deadline) can always be reprints from DC's glory days.
