Oh, don’t change it! Or at least don’t change it too much!
Polythene Pepper is kind of a nice compromise.
Day Tripper?
how about Girl with Colitis Goes By
Stick it in the Pepper!

How about… Sgt. Pepper’s Girl? 
I personally like pepperlandgirl as her name. Maybe just capitalize and add a space.

P-Sizzle.
I Am Not The Pepperwalrus
It’d confuse people because you’re not British, but Liverpudlian is a snazzy word.
This literally made me L-O-L.
Sometimes when people address me here, they do do that. Pepperland Girl. Or just Pepperland. But because I’ve had it lower cased and one word for so long, it looks really, really weird to me.
I would love to use that actually, but we have a paperbackwriter on the board (though I don’t think he posts here anymore) and so I might be stepping on some toes there.
It sounds like a sandwich! (Doesn’t it?)
I really like Quarrygirl. It’s just clever enough.
So far, I have Polythene Pepper, PepperLG (my husband says it sounds like a cell phone though), Quarrygirl, CremeTangerine, The Yoko Factor, and from my sister’s suggestion, The Pepper Factor (though I think that might just remind people of Billo the Clown).

You Don’t Look Bluish
From another Wilco song: Box Full of Pepper.
We’ve got one of those. He’s a bloke IIRC.
I could have sworn we also had a Miss Kitty Fantastico but a search reveals only a Miss Kitty
Wuppers. I just went back and listened to that song again. Um, suggestion canceled.
