None of the SRAM electronics work for what you need mate, as one lever is for shifting up, the other for down...
Try and find a bike with Di2 if you want to go electronic ... The new Ultegra Di2 should be out soon, or if you prefer flat bar bikes, there's also Di2 for XT/XTR, which I believe will also work with road derailleurs (but haven't seen it confirmed yet)
