I’m not sure if we add a larger amount of the products there because you are the only one who asked about this at this moment. So, if you want to change this we can try to help you only by minor additional customization.
Unfortunately, our theme or WooCommerce plugin do not have the options you asked (to show weight on the grid, subtitle or payment rate), so either look for the third-party plugins that allow you to implement that or submit additional customization request here.
