I ask because I was thinking he would have been excellent on the Teen Titans. Reason: I think he wrote good teen heroes (Spidey, X-Men, Johnny Storm, Rick Jones) and, of course, team books.
It also occured to me that the Teen Titans were similar to the Avengers line-up after Thor, Iron Man and Giant Man quit. (Robin/Captain America, Kid Flash/Quicksilver, Speedy/Hawkeye and Wonder Girl/Scarlet Witch).
Imagine the Teen Titans with real personaities, a little conflict in the ranks and sub-plots. Perhaps Stan could have retained his editor/writer status?
I've often tried to imagined what a Lee/Kirby Justice League of America would have been like.
Just imagine ... Stan Lee and Steve Ditko move to DC around 1960
Peter Parker from Smallville wins a Science competition in Metroplolis. First prize is a trip with Superman to meet some of the Scientists in the Bottle City Of Kandor. Whilst there Parker is involved in a terrible accident that requires a blood transfusion from the only nearby suitable donor - Superman!
When he returns he finds he now has some of Superman's powers. Reflecting the early abilities of Superman, he can now leap over tall buildings, run faster than a speeding bullet and is more powerful than a locomotive.
Parker returns to Smallville, and Aunt May and, inspired by Superman, becomes Superboy II.
If Stan had gone to DC, that probably would have put DC in the enviable position of having no real competition in an industry that needed it at the time....And it doesn't need it today ???????????
