My affinity for the hilliest of triathlons has led me to a setup where I have the PD Airstryke bar:

Clipped onto an aero road bike. That bike (Fuji Transonic) is running Ultegra Di2 with the dual control levers, and has the 3-port junction box under the stem.
Can anyone think of a way to get a rear derailleur control (at minimum) up near my fingers on the aero bars?
I know the proper/expensive way to achieve this would be to buy the 5-port junction, buy the TT shifters, and switch out the closed bar shape for two standard ends. I'd like to avoid this.
There are the dedicated sprint/climbing shifters. It seems some of these can plug directly into the dual control levers (?), where I could then run any wires under the bar tape and up through the aerobars where I'd hack some attachment strategy. I don't think these are designed for this, though, and the wires would be much too short? I've heard manually splicing the wires is quite difficult, and there is no supported way to extend the wires (sans, maybe, a "B" junction box that I'd have to hide somewhere?). Any grand thoughts on how to cleanly achieve this? Maybe the 5-port junction and one of the dedicated shift buttons would be easier?
