Use alternate template with if/else statement

I would like to add a line to this bit of code so that if it is the “$Shop_page” page use archive-shop.php template instead of the “Echo” line of code that is in there now.

I am not sure how to write this code…OR if its even possible to set this up this way.

I basically want to customize my SHOP index page. Right now it shares the archive-products template in my files. If I alter this file the changes appear on all category pages which I do not want.

Thanks!

CODE:

<?php if ( is_search() ) : ?>
				<?php
					printf( __( 'Search Results: &ldquo;%s&rdquo;', 'woocommerce' ), get_search_query() );
					if ( get_query_var( 'paged' ) )
						printf( __( '&nbsp;&ndash; Page %s', 'woocommerce' ), get_query_var( 'paged' ) );
				?>
			<?php elseif ( is_tax() ) : ?>
				<?php echo single_term_title( "", false ); ?>
			<?php else : ?>
				<?php
					$shop_page = get_post( woocommerce_get_page_id( 'shop' ) );

					echo apply_filters( 'the_title', ( $shop_page_title = get_option( 'woocommerce_shop_page_title' ) ) ? $shop_page_title : $shop_page->post_title );
				?>
			<?php endif; ?>
