You can get this by renaming and hard-linking in the /dev directory to modify the existing devfs image presented to the user. Basically, you use rc.local (or rc.devfs, if you think a period is a better subdirectory delimiter than a slash, and are dead-set against rc.d because of anti-SysV sentiment).
