My point is to make Anakin not a very convinced person of what he's doing while he slaughters all the Jedi. He's pushed to do it, for a major reason, Padme. That bullshit of Anakin with yellow eyes when he kills the children is absurd. What is he mad at?? Besides a Vader non suited would imply some people to know that Anakin Skywalker is Darth Vader... when this must be a secret to the galaxy. I think, what'd be best, is to replace Anakin and the troups entering the Jedi building in Coruscant, by a suited Vader doing so, at the end of the movie. This woul imply of course a whole re plot in some points...
