I think you are, unfortunately, S.O.L. Your choices are:

1. Custom/$$$ to get what you really want
2. Use the VO and find a way to live with the bulkiness
3. Don't use a tall stack stem

Note that the bar clamp diameter is 31.8, not 26.0, so a shim is needed w/26.0 bars. Which kinda stinks with a cut-out removable face cap like this. It offends me aesthetically. It besmirches my lovely machines. I have nothing but 26.0 bars in my fleet, so as much as I really like the un-shimmed look, it's a no-go.

Also note that Compass/Jan Heine has a nicer fillet-brazed Nitto tall stack stem, also 31.8/31.8, for $215. That can't be too far away from custom-built pricing, but they are purty. They do not have removable face caps, though.

I also found an ugly/cheapish Civia (maybe?) tall-stack stem while search engining, like for city/hybrid bikes. 31.8 steer tube, didn't check bar diameter 'cause they were not pretty, to my eyes.
