Can confirm that this is a bad idea as manfuarcturing defects do happen. Took a shipment of brand new NetApp toasters this year and they all had the same WWN/WWPN's! Needless to say NetApp where quite embarrassed and we are glad that we noticed it in pre-prod otherwise it could have been quite bad.
