I'm sure that there are more than a few people who'd be interested in hacking Di2 to work with a triple, but there are several problems.

1) you'd need to take apart the front derailleur and replace the cage with one for a triple FD. I suppose you could buy a sacrificial 6703 FD, take the cage and toss the rest.
2) you'd need some special equipment to reprogram the system. It retails for $200 in the U.S.
3) (the real problem) you need special hacked firmware that supports a triple. To my knowledge, it does not exist because no one figured out how to do it. It is not easy to hack firmware for some obscure electronic device without any source code or documentation.
