Feel free to do so.  Note that you'll hit 2 problems:

1) In the kernel, the sysadmin can almost always get away with saying
"I have no XYZ devices" or "I only have ext4 filesystems" or similar choices,
and have the resulting kernel still support basically all the syscalls
(unless you start going into CONFIG_EMBEDDED and doing some *major* surgury).
Over on the X side of the fence, there aren't as many options that don't
involve dropping major chunks of the functionality.  You *sure* that nothing
on your system depends on the XRandR extension? ;)

2) Lately, the X server is *already* highly modular and different components
built from different source trees.  Note that the base X server is only about
half the size of the kernel RPM - there really isn't much left to trim out of
the base server anymore.
