I didn't think "Brainatra" would be an appropriate user name for a Superman-oriented forum (though "Pinky and the Brain" does have a connection to Superman that'd be on topic here, via the episode "Two Mice and A Baby"---the mice apparently are on Earth-One 30 years ago and briefly take in the infant Kal-El after he lands on Earth...). Hence, "Johnny Nevada."
Johnny, there's a hilarious Pinky and the Brain / Pre-Crisis Legion of Super-Heroes crossover at fanfiction.net.

Cute...
In a similar vein, I once wrote two fan fiction stories using the lab mice, where they teamed up with Superboy (once when he was a teenager, the other time as a junior in college). I also threw in Superboy in two other Animaniacs-related stories as cameos...
Back on topic...
One more possible Supergirl/Superwoman to mention:
1980's "Superman Family" #200(?) featured a look 20 years into a possible future of Earth-1, with a married Lois and Clark and (relevant to here) Supergirl now calling herself "Superwoman".
This was the only appearance of this possible-future Superwoman, with (far as I know) no indication this was necessarily the "official" future of Earth-1...
