I briefly spoke to one of the Techs at my Bmw dealershio and he said it's possible and that a few people have been looking into it.
Didn't go into details with him but hopefully i'll find the time soon enough to go and have lunch with the guy and try and get more info.
This is by far the number 1 Mod i am dying to do on my car...
