On the topic of outside thinking, perhaps MG is the DeVoes’ daughter from a future where The Thinker’s Enlightenment is successful. She becomes a speedster due to her father, either because of all the dark matter that he’s accumulated from the bodies he stolen or because he is the only one still capable of building devices that can harness dark matter. When MG realizes that her father is evil, she goes back in time to stop him from succeeding.

For the record, I still think MG is the time remnant of Barry and Iris’ future daughter from the original timeline; I’m just throwing out a possible “outside the box” suggestion.
