yea just drill it. looks cool

Awesome!

We used to have to before cable hangers were widely available. I never had a problem on the half dozen I did.

Jesus. When I saw that drilled PRO I literally went

Drill all the stems! How much is a WCS these days anyway?

Or maybe you could use some Nokon housing to make the bend work without having crappy lever feel.

If you have a spare couple of milimeters, Humble Frameworks has made some hangers that are ultra thin when mounted under the stem.
There are some pics on the site of one of their CX bikes, a green one, with such a hanger - give it a search.
Note: I asked them twice for one of these hangers and never got a commitment... so I switched to mini-v's (sadly).
