I agree with you Tinamaree. The almond would overpower the cookie. You might try pecan flavoring.
The important thing is to keep the integrity of the chocolate chip cookie. There's only one chocolate chip cookie and everybody knows how it tastes how it makes them feel and what memories It evokes. It's an American classic. So the expectation for how the cookie tastes is there from the start. Try not to stray too far from the simple, rich taste of the cookie.
