Instead of duplicating the service, you can use service escalations,
as defined in the docs [2].  This will esentially do the same thing
you have with the duplicated commands, however you'll still need new
contacts to send the notifications to the SMS rather than the regular
emails.

The other way to handle it would be a custom notification script which
you use for notifications, and pass in the arguments for the SMS
number, the email address, the usual macros, and the notification
count [3].  Then you can throw some logic in the script that does
something like this:

if ($HOSTNOTIFICATIONNUMBER > 5) {
  send_sms_message();
}
send_email_message();
