Yes definitely - particularly if you program the DI2 to handle both derailleurs with one shifter (as mr_pedro explained).

Personally, I didn't see much point to DI2 until I got a bike with it. It rocks for lots of reasons, and this is one of them. More generally switching chain rings is much easier and I do it much more often with DI2. On my old bikes, I'd always wear out my big chain ring several times and basically never need to replace the small chain ring. On the new bike, the wear is going to be more even (though of course, I still use the big chain ring more - I live in the midwest, not in the mountains).
