Obviously in such a scenario Qui-Gon would be Skywalker.
That could be easy enough to show for a death scene flashback of some kind but there isn't enough footage of Darth Maul to have it seem he was ever friends with Qui Gon before killing him, you could never portray a betrayal. Unless you are suggesting Palpatine take the role of Vader and Maul is simply the weapon he used, but again I don't think there is enough footage to suggest this between those characters.
