Just to add to the other solutions. This method will require no jumping and you can just rubberband your controller to come back later to do something else in the mean time.
Basically put the same settings Senate, Duel, off, and No in Arcade Mode. But instead of jumping off the edge of the senate pod, go to the back walkway and fall inbetween pods. Put a rubberband on your analog stick to make your character fall down, come back later, and cheevo unlock! Easy!
