Purely from a BIND standpoint it should be just as easy to edit the default and www records as any other, it's just that it doesn't seem that DH wants to let us. I can understand that this is to keep the bulk of general users from breaking their DNS service, but it's a bit of a pain waiting on support when I know exactly what needs to be done. I'm not keen on changing the NS records because it's a temporary change and the propagation time would have been more of an issue than the server being down since the cluster has since come back online.
So right now it's really a moot point, but thanks for the reply. o.<d
