HMMM....cool idea! I've been interested in Glimmer since I rewatched the Secret of the Sword for the first time since childhood. I wasn't sure about how her powers would be used, but since Shokoti works on darkness, Glimmer would be a worthy opponent!
*sigh* This does remind me that we probably won't see this awesome silver version when we get her, though. Probably just the Filmation version with the blue.
