ah yeah thanks, i got it by editing the wc-template-hooks actually:
add_action( 'woocommerce_after_shop_loop_item_title', 'woocommerce_template_loop_add_to_cart', 10 );
But i had the trouble that add to cart button was still thrown out of the item since both are links. Is there a way to overwrite that behaviour? For now i change add to cart to a span.
