Well, EG Trixie is still a self obsessed narcissist who loves theatricality, talking in the third person, and using smoke in entrances and exits... so, essentially, she already is Dark Wing.



As for Nega Duck and Sunset... well, both are the only ones to wield actual weapons in their respective universes. Nega Duck loves a good chainsaw and Sunset is the only character in MLP ever to use a Sledgehammer with the purpose of destruction. And both are competent characters who team up with incompetent characters (the human five and the Fearsome Five)
