In latest version 3.0.* Woocommcerce used to hard check the $post_type === 'product' You can override it

class My_Product_Data_Store_CPT extends WC_Product_Data_Store_CPT implements WC_Object_Data_Store_Interface, WC_Product_Data_Store_Interface {


    /**
     * Method to read a product from the database.
     * @param WC_Product
     */
    public function read( &$product ) {
        $product->set_defaults();

        if ( ! $product->get_id() || ! ( $post_object = get_post( $product->get_id() ) ) || 'product' !== $post_object->post_type ) {
            //throw new Exception( __( 'Invalid product.', 'woocommerce' ) );
        }

        $id = $product->get_id();

        $product->set_props( array(
            'name'              => $post_object->post_title,
            'slug'              => $post_object->post_name,
            'date_created'      => 0 < $post_object->post_date_gmt ? wc_string_to_timestamp( $post_object->post_date_gmt ) : null,
            'date_modified'     => 0 < $post_object->post_modified_gmt ? wc_string_to_timestamp( $post_object->post_modified_gmt ) : null,
            'status'            => $post_object->post_status,
            'description'       => $post_object->post_content,
            'short_description' => $post_object->post_excerpt,
            'parent_id'         => $post_object->post_parent,
            'menu_order'        => $post_object->menu_order,
            'reviews_allowed'   => 'open' === $post_object->comment_status,
        ) );

        $this->read_attributes( $product );
        $this->read_downloads( $product );
        $this->read_visibility( $product );
        $this->read_product_data( $product );
        $this->read_extra_data( $product );
        $product->set_object_read( true );
    }


}

Then include this file via hook;

add_filter( 'woocommerce_data_stores', 'my_woocommerce_data_stores' );

function my_woocommerce_data_stores( $stores ) {

    require_once PLUGIN_PATH . '/includes/classes/class-data-store-cpt.php';
    $stores['product'] = 'MY_Product_Data_Store_CPT';

    return $stores;
}

Use this filter to provide the price from custom meta;

add_filter('woocommerce_product_get_price', 'my_woocommerce_product_get_price', 10, 2 );
function my_woocommerce_product_get_price( $price, $product ) {

    if ($product->get_id() == 815 ) {
        $price = 10;        
    }
    return $price;
}

Now if you try adding to cart using url param add-to-cart=[POST_ID] like http://localhost/wordpress/cart/?add-to-cart=244 will add the item to cart.

You can also use button to add to cart.
