Well, there is a simple wellknown solution without thinking in duplicates. 
That solution is called searching for the data.
It is even already partly implemented as views are searched for, so that concept is known
within bind except that currently the search stops at the first matching view.

For finding a zone no extra configuration is needed, as currently several matching views
must be considered a configuration error.

For finding a missing resource record a single parameter may be needed to allow searches
to continue after the zone has been found. 

It is conceptually very simple and backwards compatible.

If used, this may have performance implications, but what doesn't have that.
