No, you can do it with CNAMEs

$ORIGIN 12.168.192.in-addr.arpa.
8 IN NS ns.customer.net.
8 IN NS ns.isp.net.

9  IN CNAME 9.8
10  IN CNAME 10.8
11  IN CNAME 11.8
12  IN CNAME 12.8
13  IN CNAME 13.8
14  IN CNAME 14.8


Delegate 8.12.168.192.in-addr.arpa to the customer and have them maintain 
a file like:

$ORIGIN 8.12.168.192.in-addr.arpa.
    IN NS ns.customer.net.
    IN NS ns.isp.net.
9   IN PTR host1.customer.net.
10  IN PTR host2.customer.net.

With appropriate SOA etc.
