Reverse Delegation

We just started using a new ISP for connectivity at our offices. They're
a reseller of another, national ISP.
I'm trying to get them to set up delegation of reverse DNS for our
network. I believe the reseller has some access to the larger ISPs DNS
systems so that they can set up PTR records or CNAMEs in the in-addr.arpa
zones for their customers. I'm not sure that they can create NS records
to delegate subzones, however.
Instead of them doing a fairly standard RFC 2317 delegation, as we've
always done with our providers
0-26 IN NS ns1.mydomain.com.
IN NS ns2.mydomain.com.
$ORIGIN .
0 IN CNAME 0.0-26.95.104.199.in-addr.arpa.
1 IN CNAME 1.0-26.95.104.199.in-addr.arpa.
2 IN CNAME 1.0-26.95.104.199.in-addr.arpa.
etc.
would the following, without creating a delegated subzone, work just as
well, or are there potential problems?
$ORIGIN .
0 IN CNAME 0-officenet.mydomain.com.
1 IN CNAME 1-officenet.mydomain.com.
2 IN CNAME 2-officenet.mydomain.com.
etc.
