There's taking inspiration from anime and manga and then there's saying I SAW THIS COOL THING IN AN ANIME AND YOU SHOULD PUT IT IN BECAUSE IT'S COOL AND I KNOW WHAT COOL IS 'CAUSE I'M A COOL EXPERT.

Not really my thing, but I'm all for more variety in male outfits so sure, put it in. Depending on what kind of "jacket" is used as cape, I would even consider using it.
