Yes. We can change product attribute set programmatically. I prefer to create massaction in catalog product grid to multiselect product and then select massaction for the products.

Creating massaction in grid.php

$sets = Mage::getResourceModel('eav/entity_attribute_set_collection')
                ->setEntityTypeFilter(Mage::getModel('catalog/product')->getResource()->getTypeId())
                ->load()
                ->toOptionHash();

$this->getMassactionBlock()->addItem('changeattributeset', array(
                'label'=> Mage::helper('catalog')->__('Change attribute set'),
                'url'  => $block->getUrl('*/*/changeattributeset', array('_current'=>true)),
                'additional' => array(
                    'visibility' => array(
                        'name' => 'attribute_set',
                        'type' => 'select',
                        'class' => 'required-entry',
                        'label' => Mage::helper('catalog')->__('Attribute Set'),
                        'values' => $sets
                    )
                )
            ));

Creating controller action for change attribute sets of the selected products.

public function changeattributesetAction()
{
    $productIds = $this->getRequest()->getParam('product');
    $storeId = (int)$this->getRequest()->getParam('store', 0);
    if (!is_array($productIds)) {
        $this->_getSession()->addError($this->__('Please select product(s)'));
    } else {
        try {
            foreach ($productIds as $productId) {
                $product = Mage::getSingleton('catalog/product')
                        ->unsetData()
                        ->setStoreId($storeId)
                        ->load($productId)
                        ->setAttributeSetId($this->getRequest()->getParam('attribute_set'))
                        ->setIsMassupdate(true)
                        ->save();
            }
            Mage::dispatchEvent('catalog_product_massupdate_after', array('products'=>$productIds));
            $this->_getSession()->addSuccess(
                    $this->__('Total of %d record(s) were successfully updated', count($productIds))
                );
            }
            catch (Exception $e) {
                $this->_getSession()->addException($e, $e->getMessage());
            }
    }
    $this->_redirect('adminhtml/catalog_product/index/', array());
}
