Speaking of official R63, here is a little anecdote of something that could had happened.
Back when Bruce Tim was working on the early concept of the Justice League cartoon, the network wanted to the show to be about younger heroes working along side the league, similar to Young Justice. In one of the pitch for the series you can see a female version of Cyborg fighting along side the heroes.
Is fun to imagine what would had happened if they went with that idea. This was way before the the Titans show, most people would probably never heard about Cyborg. It could have been possible than that version of Cyborg would have become popular to the point of being the "Canon" Cyborg most people are familiar with. https://www.youtube.com/watch?v=aCVKlb5hqV4
