Hmm, those symlinks would look ugly, but of course
/usr/lib/kernel/<kernel-version> would be the sane name.

Anyway, as a first step, I would put just put the kernel, System.map, config
and any precompiled initrd in the modules directory:

# ls /lib/modules/3.18.0-0.rc0.git9.2.fc22.1.x86_64/
System.map
config
initrd
vmlinuz
....
