Then at point B I will setup a rigid cable bracket that will run from the bolt location that used to retain the rear fender but will now be used to keep the cables in a stable position. I believe this will be adequate, correct me if I am wrong or you have reservations. I had wholly considered the traditional MX routing pattern but opted against it for a variety of reasons.
As long as the flexible brake line is stabilized/fixed a bit ahead of the banjo that should be fine for strain relief, your mount at point B is what will take the flex in that case.
