I'm all for Glimmer. I never watched POP as a kid, but have just finished the first box set of DVDs and have been converted to a fan. A few years ago I wouldn't have wanted one, but now I see how POP fits into the scheme of things, and and how much less lame it actually is than I first thought.
So yeah, Glimmer me up. I'm sure they'd do a great job making her, just like everyone else so far. I don't think her story needs to change any either, it fits with what's going on.
Except her real name can't be Glimmer of course. I'd go with Jocasta Glikkamm'i'd'anne.
