All right this may be my dumbest question yet. However I don't claim to be a bike expert or a brain surgeon.

Considering the somewhat steeper angles that at least some "Ergo" bars have will they work with a traditional quill stem assuming the stem clamp / bar diameters match.

I'm really interested in Ergo bars as they look to me like they would be far more comfortable then a traditional bend. However Rivendell wouldn't agree from what I see on their web site.
