No - you can't exclude your wife. Excluding your wife is misrepresentation (lying in your application). If CIC discovers the misrepresentation, you can expect your application to be refused and to be issued a five year ban from entering Canada. If somehow your application is still processed (i.e. CIC doesn't discover the misrepresentation), then you will never be able to sponsor your spouse for PR and if CIC ever discovers your misrepresentation in the future, your PR status could be revoked.
