So Wendy can move her legs, just not support her own weight? (They change positions through out the panels.) That...that kind of means therapy and exercise might give her back some walking capabilities.
Also, didn't Wendy rebuild Cyborg back when she was with the Titans? Isn't she supposed to be some genius wunderkind? Why doesn't she just build some kind of implant to fix her spine? Her paralysis isn't as bad as Barbie Doll's.
*sigh* I'm beginning to appreciate the WiR trope for all the wrong reasons. Kill a woman, it drives your guy protagonist to drive forward, build a giant robot, and wage an action packed war against the bad guys. Kill a man, and you get a story about accepting your disability and eschewing the technological bounties of your world. I don't know about you, but I'm not much for eschewing technological bounties.
