I wouldn't call myself an expert, but...

With everything I've read and researched, prior to this, I've come to
the conclusion that this would take a considerable amount of time and
effort.  The resulting installed system would only vaguely resemble
CentOS on the surface.  Would require a non-standard, most likely self
created and maintained, repository for yum updates.

IIRC this would require patching and recompiling the kernel, newer gcc
and recompiling a significant number of other binaries...

Maybe you could call the new distro XentOS.

Please correct any errors of misconceptions I have.
