I'd also be interested in John_T's comments on this one, but the only thought occurring to me is that the legal ramifications will only become apparent if you havta face the judge. And the only reason that'd happen is if this practice resulted in a prang, for some reason. In that event, I suspect that you wouldn't have a legal leg to stand on - i.e. it WOULD most likely be determined as pilot error.
Having said that, I do pretty much the same thing all the time in the Kingair. Nothing has ever gone seriously wrong for me ... so far!
