If the cartoon taught us anything, it's that they all need really neat haircuts for that purpose.

On a semi-related note: did Lucas decide to make the clonetrooper bodies CGI in episode 2 in order to make sure they really were identical in height, size, etc? Obviously, the results now look like a Sega Dreamcast era videogame, so it was by no means successful. But I'm wondering if he at least had a valid reason like this.

It was probably mostly just to prove that he could, for cheap. A big goal of the prequels was to make the movies for less money than expected, while doing things that were only sort of good-enough-looking.
