WooCommerce category page layout [on hold]

My site has only 3 categories and I want to list them like this to fill the shop page, but products to remain in grid layout.

My woocommerce structure is: in my theme folder I made a woocommerce.php and a woocommerce folder with templates files from plugin directory Templates. I cannot make changes in my mytheme/woocommerce/archive-product.php because mytheme/woocommerce.php has priority over.
