I know Marvel owns Miracleman and can therefore use his original name Marvelman for another character, but Vance should stick with Justice.
Spidra as a new name for the third heroic Spider-Woman? The name sounds good, but Mattie's dead (I do think they should've left her alive after she was resurrected in Silk's Clone Conspiracy tie-in - the clone degenerated like most of the others).
Who are Ultra Woman and Lightbright? I've heard of Ultragirl (one of Carol's proteges before Kamala came along, a teenage girl who happened to be half-Kree, like Carol later turned out to also be), but not an Ultra Woman.
