I do this all the time too, but if the new kernel doesn't boot, you
end up in more trouble than needing an extra reboot. The reboot part is
definitely important -- you can reboot into multiuser mode and do the
installworld that way, but if you have the new utilities and have to
drop back to an old kernel, you may have to reinstall the base system.
