Update: Finished my conversion, and I'm really pleased with how it turned out. Went with a 110mm Nitto Tallux stem from Rivendell and the VO Postino bar with Tektro FL750 brake levers. Added the Jagwire braided cable and some Brooks leather grips as well.

Ride is very comfortable and I like the look - a little more upright but not too much (stem could actually go higher but this feels right). I can see riding this around the neighborhood as well as on longer treks, since it's got the nice long touring frame with the ability to add racks and fenders.
