Having no expertise whatsoever I would say no. Though I might say being deaf in and of itself would be equivalent to speaking one of the mentioned languages on some level. Each language's structure and phrasing gives a different window onto thouight that I don't think is matched by using hand gestures in loo of vocalizations. But I should re-enforce that I don't have a clue how sign language is actually spoken, or wether it is qualitatively different than american english.
