I've never seen the full updated A New Hope but if there is a way to use the Vader suit to add a scene for ANH then It would be great to add a scene where Vader finds out the name of the pilot that destroyed the death star.

You could add a scene right after luke,han and leia walk away from the x-wing celebrating but before the ceremony. Have a scene of Vaders tie fighter landing in the docking bay of a near by star destroyer.

in that scene vader could be told what the name of the pilot who destroyed the death star is.

Hated the fact that vader finds out he has a child off screen. (For those who will watch the old trilogy first they will just think Vader is shocked to her the name Luke SKYWALKER because Vader 'betrayed and Murdered your father'. They will think Vader is thinking of Luke's Father that he had killed (but we know that lukes father....is...VADER nooooooooooo)
