I remember there was a guy who tried to do this about a year ago. It was on the poker theory forums, but I can't seem to find it right now. As far as I remember, he didn't even finish it for the case when opponents's cards are also universally known and they are sequentially allowed to call or fold. Anything else makes it a good deal harder.

It could be a useful exercise. My suspicion is that results will actually be on the other side, that is, they will suggest more conservative play than what most people would do in a real game. I think that most people tend to underestimate the chances of winning HU, but tend to overestimate the chances of winning in a multi-way pot.
