If so what is the ending result? Would the original center dancers end on the same side as their original wave and would the original end dancers end as the centers of the diamond on the other side of the square?
On Switch To A Magic Diamond, the Centers work normal; on Magic Wave Switch To A Diamond, the Centers work Magic Wave (danced as if In Tandem). In both cases, the Ends' part is the same: they end in the far center position.
Technically, Switch To A Magic Diamond is not explicitly on the C3B list, since Switch To A formation is not there. Hence, if you call Switch To A Magic Diamond, you will probably get some dancers who will do a Magic Wave Switch To A Diamond instead.
