Since his problem seems to be too many photons, this won't make a 
difference. And a truely perturbed surface will give more accurate 
results, and with large waves will look much better. A normal is only 
useful for small ripples and disturbed water, not for large waves which 
cover up further waves. A height field might do better for speed, if the 
triangle artifacts aren't too bad, but it wouldn't help his memory use 
at all.
