I'm not sure how hard to find she is, but I do have other suggestions if it turns out she's a no go. (Keep in mind only her butt is see-through.)
There was a set of glittery translucent G3s called
Divine Shine. They are pretty popular but you could probably still find a bait.
Also there were glittery translucent fakies which copied the G3 mould that many have used for customs and are available in a lot of colours. You may want to ask in the customs forum about the availability of those.
This sounds like a pretty cool custom, good luck!
