Once you take the kernel off the reservation be warned that
some packages in the repository may bork:

most likely: packages that have a kernel module (drbd, etc)
moderate likelihood: low-level api packages (glibc etc)
less likely: high-level user-space apps (apache etc)

Knowing the consequences of that, then what I might do is
try to wrap my own kernel RPM spec file, remove all patches
from current one so you have the bare spec. Keep the config
files, but for new options you may get prompted during build,
so afterwards move the BUILD\kernel\... configs into the
SOURCE so the next build won't prompt you.

This way when you install it you can remove it easily and
everything is installed CentOS appropriate.

Make sense?
