FYI, In a hotly contested draft that never made it to an RFC (which I
hate to bring up again and am not trying to start that discussion again
now), I showed that to securely add a key to the root zone, given its
parameters, you need to publish new keys for 53 days, not 30 (the
hold-down timer).  So please pick a longer period than one month should
your proposed plan get adopted.
