Constantine.
He does all sorts of magic shit and he's crass and smarmy enough to fit in the show.
Plot could be him dimension hopping for a macguffin that Panty and Stocking also want so they fight/shittalk each other

If Constantine isn't cape enough, then Fire and Ice.
Their powers should at least be somewhat useful against ghosts and they're hot enough for it to be a fanservice episode.
