I don't see anything wrong with it. Fanedits are meant to provide new experiences, and since they don't replace the original (or the "original," when dealing with Star Wars, unfortunately), who cares? And if it is done in a manner that allows someone to watch in a different order (such as 1-2-3-4-5-6), who cares about that either? It's not what you would do, but it shouldn't be any skin off your back.
So the OP asks "why?" and I ask "why not?"
