I am of the opinion that SRAM will have a 2 X 11 system available that will include a long cage rear derailleur. I would give that consideration. Wireless and 15 minute set up. I believe that the OP would have to change out the rear cranks.

That being said our Calfee with 3 X 10 shifts great using 6703 levers and Dura Ace derailleurs. Ultegra cranks 52/39/30, Ultegra cassette 12 X 30.
