I dunno, I've done some googling but got nothing
you could always order a new one and do what you want with it yourself.
Warmoth [ http://www.warmoth.com/pickguards/pickguards.cfm ] lets you order them in alot of colors and shapes. If you want some sort of awesome graphic on it, then- for lack of a better idea on my part- contact your nearest tattoo artist, they could probably do it for you.
That sounds like a wierd idea, but it makes sense i guess...
