Bicycle Mechanics - Reverse routing non-aero brake levers

I remember reading in an old issue of bicycle guide that one can route the cables of non-aero brake levers under the lever, like a conventional "aero" brake lever. Im curious to this procedure if anyone has heard of it.

Have my Merlin road bike set up as a time trial bike using Modolo non-aero levers. Using a pair of drop bars cut down and turned over as time-trial bars giving me more reach. The non-aerolevers are mounted UNDER the bar, near the upcurve part of the bar, so you cannot see the brake levers as you ride. But they are easily reachable from my aero position. The cables come thru the hole in the brake hood and are routed under the bartape.
This may not be exactly what you had in mind.

Is the cable routed down and in from the very top of the brake hood and the cable housing routed and taped along the underside and exiting out from the tip of the lever? I think this is what you're talking about? If so, yes, it can be done...

How about pictures, so we can see what you are talking about...I'm confused...

This was once very common, and was the reason why companies first made aero levers. Don't let the cable bend too much.
