Assuming the stock configuration has attached flow, I don't think there's any benefit of doing that, unless your goal is to mess around with the stagnation point.

EG: from Phil's "book illustrations" album:



The "optimum" nose has the lowest stagnation point - ie. less of the total flow will go under the car vs. above/around it.
