The only possible issue I can see, is that pulling one lever pulls both cables at the pinch bolt, possibly pushing the other housing out far enough to pop out of its hole and get caught on top when the lever's released, perhaps leaving the brake somewhat applied.

To mitigate this, you could attempt to somehow fix all the housing ends in place so the short length of exposed cable above the brake either bends or forces the unused lever to move (assuming full-length housing), drill deeper cable stops (allowing the unused housing to move up without coming out) in a bigger chunk of aluminium, or engineer some kind of fancy straddle-hanger with floating cable clamps.

That's if it turns out to be an issue.

I worried about that a little at first but didn’t experience the housings moving at all. The only thing I see is the free sections of the cable going slightly slack, hardly enough to notice unless you pluck them.

I used an inline barrel adjuster on both cables and that works great to fine tune them without messing around with the pinch bolt.

How about find an late 80's MTB frame from when they mounted U / roller cam brakes under the chain stays. Then braze some canti mounts on to the seat stays. One lever for each.

Alternatively, you could get U brake mounts brazed on to the chainstays on a canti bike. But you'd have to make sure that specific frame could handle it.

Yeah Im not going to get into brazing, just because I do not think this frame is worth repainting. I will probally build a new rig over the winter. So I will stick with a shot reach brake mounted normally and then a longer reach brake with a Metal plate mounted behind that.

You could drill into the side of that alloy part and then makes some threads and put one of those little hex screws through it (like the adjusters found on bmx style levers) to hold the cable housing there.
Also there was another flaw in my gyro cable system. On the metal bars the parts holding the bottom barrel adjusters they where attached to my stem but they would slip no matter how much I tightened them. I know there is a way I could get around this but It was getting to be to much..

BMX market has adapter plates to go from long reach side pulls to canti/v brake

such as http://billys.co.uk/english/group.php?prod=bsdnvps

or to U brakes.. a U shaped piece with 2 brake bosses.

You could get 2, bolt them on both sides if the seat stay bridge,

then get 2 of the same brake to mount onto them..

1 lever 1 brake , but since they are both on the same wheel, task accomplished.
