Although this should work, I would recommend that before someone use
either of these addresses (and in particular 10.0.0.0/24) please
consider how many other networks with that address exist.  Without
getting into the whole renumbering argument again on nanog (#include
<flame.h>), if you are able to choose a portion of 10/8 space with some
amount of randomness you can reduce the potential for conflicts in those
cases where two private networks need to merge.
