I'm not sure I understand what you are trying to do here.  Currently you
have a block that is delegated by ARIN to 2 nameservers.  You want the
*entire* block to be served by 2 different nameservers?  Unless I'm missing
something here, why not go back to ARIN and change the delegation?

If this is part of a larger block - i.e. 10.20.in-addr.arpa. is delegated to
ns[12].somedomain.com, and you want 5.10.20.in-addr.arpa. to be hosted
elsewhere, it could be done with:
$origin 10.20.in-addr.arpa.
@ SOA ns1.somedomain.com. admin.somedomain.com. 1 86400 10800 2419200 3600
5 NS ns1.otherdomain.com.
  NS ns2.otherdomain.com.
