You could probably get away with re-routing. Cutting up your cables is not a smart move. Lots of measuring, and the ends never work because they are a machined fit.
The trick is to make the cables have the biggest loop you can make. Any bend is doom to fail. Too much stress between the cable ends.
The loop my look out of place with the bars, but you have no choice. Less kinks in the cable, the easier it is for both of you. Be creative.
