I'm not at home right now but will double check the drawings when I am.

Non m E39 hub is 74.1 vs E90 72.56. Rims aren't interchangeable. That means the rotors aren't either. I'm not sure about e39 M but I assume is the same as non m e39.
You need to look at the hat. Is 50mm for e90 vs 45mm for e39. Don't just look at the center line of the blank.
