Possibly, however an intact upside down helicopter doesn't tend to drift much with the wind, whereas the visible wreckage seemed to get to the rocks quite quickly in moderate wind (not sure about the current though).
I'm a bit confused about where these heavy bits have been found - "off the southern tip of Shetland" according to the Beeb. If they are in shallow water by rocks, your theory is sound. But if nearer the original impact location, surely they must have separated at the time?
