Hi Mike,
Propagating them by clones would provide more flowers, pollen, and attract more pollinators, which wouldn't hurt in a self pollinating cultivar; however, self fertile cultivars that do better with a pollinator, which means you need a different pollen compatible cultivar. When your dealing with diploid genetics, it's rare that a single cultivar would self pollinate, and the ones that do, always get better pollination with a pollinator, meaning a different pollen and bloom cycle compatible cultivar. So the answer is yes and no, yes you may get better pollination with multiple specimens, but that's still inadequate compared to the recommendation of a proper pollinator in applied context.
Hope that helps!
