No, the point of Fett being on the Sail Barge is so that Han Solo can back at him ... even though it was fumbled. I prefer it the way it is.
In a discussion on another forum, it was mentioned that the pilot's chest boxes in ESB change from scene to scene. These are goofs that could be changed.
Let only Sev Zenesca have a chest box with a red and a green square button. Change all others so that the rightmost two square buttons are always blue and the others white: Especially Luke's.
