Not any worse a message than her gaining the ability to walk again thorough an "experimental surgery"...
Wasn't an elseworlds. At the end of her Batgirl series, Steph, under the influence of the Black Mercy, had a series of visions. One of them had Babs as a Green Lantern, Steph herself as a Blue Lantern, and Damian as a Red Lantern. (She also imagined all 3 Batgirls going back in time to team up with the Blackhawks, and both of these are stories I still really want.)
