Almost every source on Supergirl states that Kara was supposed to look after Kal-El on Earth.
It would be really interesting to see how a young teenager with superpowers manages to look after a baby while hiding from the government(s) and learning how to live on Earth.
I've seen a number of Elseworlds or Alternate Universe stories on Superman, but I've not seen any story where Kara got to fulfill her mission.
Is there any official comics or other media where Kara got to raise Kal-El on Earth?
By 'other media' I mean films (though I know where are not any), tv-series episodes (including animated), or anything at all that is sanctioned by DC. Not that I've seen any fanfiction like this either.
