IMHO:
if you' re talking about removing waste wood from inside an inlet perimeter, the answer is maybe, but it won't be as efficient as having different sweeps and sizes at your use.
if you're talking about stabbing in an inlet perimeter, the answer is no, you'll really benefit from several different sweeps.
if you're referring to lowering the field around relief carving, again, could get away with one shallow sweep profile, but again efficiency would suggest a variety is useful.
At the end of the day, I think gouge choice on any of these tasks is really a personal preference and what ya feel comfortable with after trying a few things.
