yeah I thought you might have had it, so far looking I didn't have any luck. In the search I did find on other forums people were looking for the same shots but none turned up there. Only hope is photos from one of the tours everything goes on, Don't think I took any Lyn Me photos when I went, i'll double check though.
edit adding info-
just looked it up online and Star Wars: Where Science Meets Imagination -will be next at Pacific Science Center, Seattle, Washington - March 19, 2011 - May 8, 2011 - not sure if her costume if there though or not but if any fellow dent members are in that area and are planning on going they can get a lot of pictures for you.
