I'll say it again, I've got 6,000 km on a Rotor 3D+ crank in a BSA shell with Di2- bit of grease, works fine.
From reading the thread isn't the ID of your BB shell larger in the middle? I'm certainly going to give fitting it a go when it arrives, but not awfully hopeful.
Have you sheathed the crank axle with anything?
Use a cut up youghart pot. Cut so it doesn't interfere with axle and keeps cables back
