Certain example embodiments of this invention relate to composite pillar arrangements for VIG units that include both harder and softer materials. The softer materials are located on the outside or extremities of the central, harder pillar material. In certain example embodiments, a high aspect ratio mineral lamellae is separated by an organic “glue” or polymer. When provided around a high strength pillar, the combination of the pillar and such a nano-composite structure may advantageously result in superior strength compared to a monolithic system, e.g., where significant wind loads, thermal stresses, and/or the like are encountered.
