The batteries will be much more convenenient than the hidden battery of DI2. I just don't like the battery hidden in the downtube. I do all my own wrenching. I could deal with the wires in a new build, but I would rather not. And my main interest in conversions from mechanical on old frames.
I wonder what just the derailleurs and levers will cost for a conversion...UK price.
