I thought you meant the buildroot directories would be at different
versions. But you just want to override the
BR2_LINUX_KERNEL_CUSTOM_GIT_VERSION, that's OK of course.

Since it does exactly the same as BR2_PACKAGE_OVERRIDE_FILE, I don't
see the point... Unless you want to start overriding toolchain configs.
Actually, I don't see much point to override the .config - why not just
save a different .config?
