I don't know if it would be possible given the timeframe but Mr. Incredible, Elastigirl, and Buddy Pine (Syndrome) as Mr. Incredible's sidekick would be a perfect pairing for a small group of heroes at first, in the 1940's genre.
The only thing is Elastigirl's personality would need to be tweaked to be not as assertive as she was in the film.
What if Walt Disney expands into dime novels and superhero comics , eventually has his own superhero universe of established Golden Age superheroes in the 1940es which competates with DC ?
Keeping in mind the source materials for Walt Disney's other works - fairy tales, folk stories, historical figures - Disney superheroes might follow the same path. Updated versions or pastiches of Gilgamesh, William Tell, Jim Bowie, or others would be likely.
The Kid was originally a nameless boy (who only ever remembered being called 'Kid' by his 'Gran'pa') who was killed when a U-Boat sank his grandfather's fishing boat during World War II. Due to a supernatural mix-up, however, he was killed 75 years too soon.
To rectify the error, the Kid was brought back to life for another 75 years with the mission of upholding good in the world. He was given the power to summon any good historical or mythological figure or animal by saying the word "Eternity" as well as to use the same word to make himself material or immaterial and invisible. Kid Eternity was further assisted on his duties by the clerk who'd made the error, Mr. Keeper. He is sometimes shown summoning fictional figures, like Jean Valjean
