I just think he fucked up a couple of character placements.
Specially Palpatine/Admmiral Piett and Grievous/Mace Windu.
I wouldn't doubt if Lucas stole that idea for the next cash in special-extra-deluxe-super-mega-hiper-ultra HD/BD edition of the SW collection, making it like comic book variant covers that join up to form a huge poster.
All work and no play makes me..., well, you know the rest.
