But when we realize that our practice includes everything, why don't we include the Nirmanakaya Buddha? Shakyamuni Buddha is included in our practice.

The Nirmanakaya Buddha is within ourselves.    --------------------------- Excerpt from Shunryu Suzuki lecture - 68-10-00-B as found on shunryusuzuki.com.
