Override/change reviews tab in product from module

[numediaweb]

I read in the forums that it is impossible to change the theme templates from a custom module.

 

In my case, using prestashop 1.6, I want the reviews tab to have a different title like:

Reviews (15)

and the content of the tab, i want to feed it with reviews from a different source (not using the current shop reviews saved in the DB).

 

Now inside my module I made a hook in the install:

        if (!parent::install() ||
            !$this->registerHook('displayFooterProduct') || //
            !Configuration::updateValue('MYMODULE_NAME', 'My Reviews')
        )
            return false;

Which will trigger:

     /**
     * Returns tab title & content
     */
    public function hookProductFooter($params)
    {
        $tabTitleSuffix = ' (50)';
        $tabContent = '<p>here are some reviews for you</p>';
        $this->context->smarty->assign('tabTitleSuffix', $tabTitleSuffix);
        $this->context->smarty->assign('tabContent', $tabContent);

        // Call the template containing the HTML-code of our new tab content:
        return $this->display(__FILE__, 'producttabcontent.tpl');
    }

In the producttabcontent.tpl:
 

<section class="page-product-box">
    <h3 id="#idTabeKomiReviews" class="idTabHrefShort page-product-heading">{l s='Reviews'} {$tabTitleSuffix}</h3>
    <div id="idTabeKomiReviews">
        <div id="product_ekomi_reviews_block_tab">
            {*call script that sends producttab.php content to this template :*}
            {$tabContent}
        </div>
    </div>
</section>

What is the best practice do you think/advise guys in order to make my module alter the reviews tab in product page?

 

A second question, is it possible to make it work with whatever the theme is used in the shop?
