Bike is rad, well done, you sure onow how to build a classy ride Ed. Since you've had a bike fit, made up your mind about sticking to that saddle and gotten your position dialed in isn't it possible to drill a hole through the seattube and post and have the brake cable pass through there? It would run almost parallel to the seattube yet not obstruct the rear light, look loads better and act as an e-brake when/if your seatpost slips which would be the main reason for doing so. Joking aside you could drill out two anti diametrical parallelograms in the seatpost instead of just a hole, with a height of a couple of cm's alowing you to readjust the seatpost height in the future if you needed to. The width would be that of the hole drilled in the seattube of course. I think that could work, no?
