Minor update. I saw the cyclist with external Di2 again today and got a chance to ask how it was done so cleanly.
It turns out she had the battery in the seatpost. Wires from shifters run under down tube, junction box under BB with wires running inside seat tube up to battery, then wires run to FD and RD under chainstay.
I don’t know if my bike’s BB shell is large enough to duplicate this setup, but it does look very clean and did not require any holes to be drilled (I think the hole for attaching under BB cable guides gives access to ST).
Hmm....

Or do you have two holes in your BB shell?
Regarding the room inside the BB shell, if you're running an external cup BB and a 24mm spindle crank you'll have more room to work with than running a cartridge bearing square taper BB. I probably wouldn't consider it with the latter.

Doesn't the junction box get mounted using the hole from the obsolescent cable guide?
