Hasselblad changes the camera much more then Leica did.
... but not really significantly more than the after-market grip makers. Ok, the grip is molded on, but it still is a pretty secondary part of a camera, and hobbyists have already done more fancy camera case modding without claiming to be a camera maker.
Besides, if the Hasselnex should be successful, we'll soon see Chinese shells for self-modding your Nex in many cute and fancy patterns.
