Cable stop with slamed threadless stem?

Hi yall, I have an old S-Works 26er that I'm building up and have run into an issue with the front brake. The rear has a cable stop built into the frame, but the front doesn't and there's no mount on the fork crown to install one. Additionally, the stem is slammed so I don't think a steerer tube hanger would work either. It's also 1 inch threadless so parts are a bit hard to come by. I could get a new fork or go for v-brakes instead of cantis but ideally I'd like to keep the parts I have. Anyone know of a 1 in threadless stem that has a cable stop like some quill stems do? Or any other solutions? I'm thinking I could maybe buy a different stem that's a bit shorter and get a super skinny hanger so if anyone has recommendations for those I would take any and all.
