What?
Nooooooooooooooooooooooooooooooooooooooooooooooooooooooooooo!
Angel honey... don't mess with the Grand Moff or with Leia's lines that's really unnecessary...Lucas screwed up the Vader character in the later films in the first two you get a character arc of a type forming.
In ANH he is forced into playing second fiddle to Tarkin who is genuinely chilling (unlike Darth Snore, Count Coocoo and Darth Spurious), in the second film he has the chucks pulled away and he can push people around at his leisure.
Making Vader already the second in line to the throne was the big mistake of ROTS and to some extent ROTJ.
Vader worked better as Palpatine's pitbull than his mrs.
