I actually think they would look good on a white, facelifted E53. Would be different for sure, for example X5SND runs the X6M wheels (I forget the style name but they are staggered 20s) on his facelifted E53 and it looks proper.

Are the offsets more aggressive in the wheel (more concave) or are they the same front and rear?

And like tmv said, any E70 wheels fit E53 you just need hub rings to go from E70 center bore to 72.56 center bore of the E53, easily found.
