Hi,
Yes you can use a script in order to get the height of all elements (" .hikashop_container ") in the page, get the highest and so, change the height of all other elements.
If you have jQuery in your template it will be easier for scripting it because you can make a "each" on a HTML selector (so all ".hikashop_container"').
