Same on the last point. I pretty much call everyone in the Batfamily by their real names, but the Orphan name still bugs me.
The Misfit thing was just a random idea. A traditionally "non powered", even though he totally is, mantle which I think should definitely pass to a powered character is over in Marvel. I think that, especially given her recent conflict with her original inspiration, Kamala Khan would make a better Captain America than Falcon.
