Gabriel's dead, he's not coming back, unless god says so, and he's unlikely to. And wouldn't lucifer be an even bigger threat, as far as we can tell, metatron only wanted to kick all the angels out, Lucifer wants to drive humanity to extinction (and I doubt he wouldn't kill any angel who doesn't side with him).
