Yeah. I belive that in the SW Chronicles there's pictures of the Fett costume in all white. So they went that far with that idea. I think that they thought it was too close to a Stormtrooper, so Johnston HAND PAINTED the Fett costume that we saw in the ESB. How cool is that?
In a way, they could be a simple repaint somewhere else in the line, and not a McQ fig.
