You'd have to keep very short distance between your flashes and subject (as Ken mentioned above). Or you may, for a static subject, open a shutter and fire the flash(es) several times (kinda light-painting with flash heads). Anyway, PE paper is cheap, if you have a suitable camera, you can just try.
