Probably not, Angels don't naturally have souls, or else they wouldn't simply fade upon death, thus they must gain there souls upon losing there grace and becoming human, as such it would be little different from a human soul. Plus exactly what makes a demon so powerful is never explained, Crowely's in the top seven, and he's barely four hundred years old.
