I suspect you'll be using longer-than-usual lenses. It'll reduce any distortion from body parts at different distances, Think about marking reference points. Will it be easier to move the camera or the model? Is there something the model can look at so that head movement is minimised. I know you can get wheeled mounts for standard tripods, which could make camera movement a lot easier. Usual for video, rather than still photography. Minimum, I think, is markers for the model's foot positions, and a target marker at eye level. Because of the lighting, I expect it will be easier for the model to turn in place, Consider a sheet with something like a compass rose -- a circle to space the feet combined with direction markers so that each step in the rotation is the same angle. Does that make any sense?
