No, this does not work.  You're forgetting what goes around the example
records:

domain.com. IN SOA ...
domain.com IN CNAME x.y.com.
domain.com IN NS ...
www.domain.com. IN CNAME x.y.com.

This is not only against the standards, but is nonsensical when you
consider the semantic meaning of CNAME "for all data related to domain.com,
please see x.y.com".   That doesn't make sense when there are also other
records present at that owner name.
