The prequels have little story as it is. Removing a whole character would not only be difficult (and I second Angel's question of whether you know how you'd go about removing him as an element) but would probably mess up the story.

A far more realistic undertaking would be a redub, so that we might actually start to like his character.

I think Jar-Jar should be more like 3-PO was in the OT. He needs to be smart and still not liked by the other characters. Redub him with an english accent. Hell the characters hated threepio but we all loved him.
