Anyone who comes up with a list of intentional similarities between Marvel and DC and lists Deadpool and Deathstroke but not the X-Men and the Doom Patrol should be ignored. Also, that doesn't answer the question. And for the most part, this is a stretch. Also, I'm annoyed at your weird inconsistency in the order of naming them. There are so many things wrong with that that I don't know where to start.

Many characters share similarities, because there are only so many archetypes and themes. Even within companies, there are copies. Green Arrow is Batman with a bow. Guardian is copied from Captain America? They were both created by Kirby/Simon so they could reuse stories. Is every sidekick a Robin copy? Is Supergirl just a Mary Marvel rip-off?

To answer the question: Gail Simone is probably the best known example in comics. In DC animation, the late Hilary Bader, who started out writing Star Trek fanfics. Those are specific examples. There's always "was inspired by a certain work to write their own", but that doesn't count. Because that's practically everyone. Including RWBY.
