Create the two child zones that you mentioned.

When you have signed 207.151.in-addr.arpa and are confident that it validates 
correctly, you will need to get a DS record published in the parent zone, 
151.in-addr.arpa. That zone is operated by the RIPE NCC, and so you will need 
to talk to them.

When each of your child zones is signed, you take one or more DS records from 
each child zone and publish them in the 207.151.in-addr.arpa zone along with 
the NS records.

There is no need to do these in order (in the sense that nothing will break if 
you do these two steps in a different order), but you will need a secure 
delegation from 151.in-addr.arpa to 207.151.in-addr.arpa before secure 
delegations from the 207.151.in-addr.arpa zone to your children are useful 
(assuming validators that carry just a root zone trust anchor).
