So apparently this is a big no-go, but I’ve been able to build my own custom comments form and loop using this code:
<?php $args = array(
'post_id' => $post_ID);
$comments = get_comments($args);
if($comments) :
foreach($comments as $comment) :?>
<div class="comment"><?php print_r($comment); ?></div>
<?php endforeach;
endif;?>
