For the cross, there is one lead to move the leg and a separate distinct lead to shift the weight. The leader's aim needs to be good and he must not move the follower's body too much to the side as they rotate. (This is super subtle). The followers need to focus on being together with the leader through the whole of the step rather than just at the beginning and end. If both can do that, then you can lead a cross which doesn't actually change weight on purpose.

This opens up a lot of cool possibilities. But, maybe even more important, it makes the basic more rich and satisfying. Then, when the Follower crosses and changes weight, every part of that is together and on purpose.
