I had an idea many years ago that would work for this…
Since I always liked The Teen Titans as a group of sidekicks rather than just teen heroes, I always thought it might be fun to see some of the ones who were not sidekicks portrayed as if they had been at one time.
I thought a fun Elseworlds story might be to cast Steel (John Henry Irons) in the 50s and 60s era of DC comics with Cyborg as his sidekick, who would end up being a founding member of the original Teen Titans, alongside Aqualad, Kid Flash, Wonder Girl, Robin, and Speedy.
Steel and Cyborg cover a lot of the same ground as tech experts using machinery to enhance their abilities, albeit in different ways. Yes, I am well aware that Cyborg’s existence as a character pre-dates Steel’s, but Steel was always portrayed as a confident, noble adult and most of Cyborg’s existence portrayed him as a young teen, associating with other young teens. I think having them team-up, even for a one-shot, as mentor and sidekick would make for a fun, throwback-style comic, starring characters who didn’t even exist in the era being saluted by the story.
