That isn't necessary, because Mach 3.0 already works on PPC. I am working 
to get the Hurd running on it (although I haven't made much progress for 
a few months because of a hardware problem).

The Hurd could be ported to Darwin (it has most of the Mach interface), 
but then support needs to be added everywhere for the IOKit and other 
things changed by Apple.
