specific single product template for category in Woocommerce

Hello Guys,

I'm trying to show a different product category using the Avada theme.
But It doesn't matter what I do, I just can't get this to work.

The files I have are and can be found in: child-theme/woocommerce/single-product/
- product-image.php
- product-thumbnails.php
- short-description.php


- product-image-custom.php
- product-thumbnails-custom.php
- short-description-custom.php

So I want the the files which ends with custom.php to show up in 1 specific woocommerce product category.

I've tried adding in my functions.php:

<?php if( has_term( 'MYSPECIFICCATEGORY, 'product_cat' ) ) {
    $file = 'product-image-custom.php';
} else {
    $file = 'product-image.php';
global $woocommerce;
load_template( $woocommerce->template_url . $file ); ?>

Also tried this:

<?php if (is_product_category( 'MYSPECIFICCATEGORY' ) ){
    wc_get_template_part( 'content', 'product-image-custom' );
    wc_get_template_part( 'content', 'product-image' );
} ?>

Both things does not work? It will show me or the custom template on all products or it just won't work. So what am I missing here?

Also the theme has no single-product.php file.

Hope someone can help me with this because I'm getting headaches haha!

Thank you for your help!
