I don't know about your set up, but I just tried this on my bike (I fucked my arm up on the weekend and can't put any weight on it). I thought your idea was brilliant and this would at least let me get around without too much pain until healing does its thang. For it to work (sit straight, all weight on the seat, what I suspect you're after) I would have had to lower me seat a lot. The result would have been pretty funny I imagine. A la that cop at the Tibet protest (olympic run).
Not sure if this is a helpful post, but it's worth considering.
