We danced this one last weekend, and it works quite well, even if the "dolphin" couple doesn't quite get the "switch leads without switching places" bit. As long as they wind up in the center, it works.
Passion for Dolphins
A1 Down the hall, 1s in the middle. Turn alone, come back, end with all facing Lady 2.
A2 Full dolphin hey by the 1s, starts with Gent 1 passing Lady 2 by the right.
B1 Ones swing in the middle of the set (8) (end facing down) and roll out to swing N (8) (progression).
B2 LL F/B. 2s (below) gate their new ones about 1.25, to a new line facing down.
