1)  The tower is not a protected landmark.  It is a landmark by definition, but not protected.
2)  It could still work with a swing ride.  The ride would have to be programmed to start swinging after it rises above Tatsu and to stop before it gets to the ride on the way down. I don't know the distance between the track and the tower.
3)  The loading platform could be built above the track so it never comes in close to the ride.
