No.  Kernel modules must be built using the .config file in
/usr/src/linux and are specific to the things that are specified
therein.  It is not possible to compile a standalone module for any
scheduler (or much of anything else, for that matter).  (It is possible
to change the source to a previously compiled module and RE compile
that.)

Sorry, your life cannot be made easier.

Jim DiGriz' (a nom de plume for Alexander Clouter - whose name I've just
misspelled) stuff is "the place" to start:

Yes, certainly.  You'll also have modules for u32 and (e)sfq and perhaps
others like ingress policing loaded all at the same time.
