Did you tried to pass -DNO_CLEAN -DNO_KERNELCLEAN -DNO_KERNELCONFIG -DNO_KERNELDEPEND -DNO_KERNELOBJ options for make universe over the already built tree ? When I develop, I use make buildkernel -DNO_KERNELCLEAN -DNO_KERNELCONFIG -DNO_KERNELDEPEND -DNO_KERNELOBJ unless I change config, or add a file, or add a module etc. This combination gives me seconds for whole kernel and modules rebuild time when I know that the build metadata, i.e. files participating in the build, and the build options, did not changed from the latest full rebuild. I think that a similar trick should work with make universe, it might be somewhat more involved to properly pass the directions, may be not. But it should give the build time in the range of tens of minutes, indeed.
