Yeah, use Life Forms and change the frame rate. It needs to be roughly 133% longer than the original for the dance to look like real time speed. Don't try to change the rate within poser or you will get a BHV related error where the character's hips will rotate on newly tweened frames. Get a demo of Life Forms at www.credo-interactive.com
