I'm sure someone has but that someone is not me. I do know that it is 
possible to install PureDarwin or OpenDarwin (Pure's predecessor) 
underneath the corresponding OS X installation. Everything continues 
working normally which suggests that if the code Apple uses isn't the 
same as what they publish then the changes have no visible impact on 
running OS X.

Doing this on more recent versions may be difficult as Apple signs code 
these days. The kernel isn't signed but some other components are.
