I like Spike, but I don't think she'd be a good fit for any superhero comics.
That the whole fucking thing about all these editors and creatives walking into Marvel Comics. They seem really qualified for literally any other genre or publisher that isn't Marvel or DC Comics. Genre fiction has its list of specifics and tropes that you hit (or at least rub against) and Superhero comics are the same. If you're handed Avengers when you'd rather be working on Archie and Betty and Veronica comics, you're not playing to your strengths and you're not engaging the readership correctly.
These editors would probably do really well at Boom! Oni Press, or Tokyo Pop. Or if they were back at DC in the early 90's/Aughts, MYX and rebooting Angel Love. They're just misplaced where they currently are.
