I completely understand your point Irish, but from my viewpoint as a GML, the costume needs to look like it walked off the movie screen. I am especially hard, maybe unfairly so, on Fetts. Boba Fett is a face character and HIGHLY recognized. So, carrying that through to the light board means that the suit in the movies didn't display TK IDs therefore, nor should an applicants.
NOW...that being said, if they have a programmable board and want to change it for non-official troops (cons, private b-days, etc.) than that is well within their right and I wouldn't say anything. BUT, at official 501st events, the board should display screen accurate characters.
