It is not possible to have views layered as you describe.  However, try
this:

file zonename.shared with all shared records.
file zone.zonename.for-the-many with the records for the many.
	$INCLUDE "zonename.shared"
File zone.zonename.for-the-few with the records for the few.
	$INCLUDE "zonename.shared"

view "for_the_few" {
	...
	zone "zonename" {
		...
		file "data/zone.zonename.for-the-few";
		...
	};
};

view "for_the_many" {
	...
	zone "zonename" {
		...
		file "data/zone.zonename.for-the-many";
		...
	};
};
