so it appears that woocommerce may be storing a comma separated list of id values? Now that I see the difference in the XML.

You could try

// priority of 20 so it runs after ACF
add_action('acf/save_post', 'my_acf_save_post', 20);
function my_acf_save_post($post_id) {
  $repeater = 'other_images';
  $subfield = 'image';
  // using get_post_meta because that way 
  // we're sure to get the image ID
  $count = intval(get_post_meta($post_id, $repeater, true));
  $images = array();
  for ($i=0; $i<$count; $i++) {
    $field = $repeater.'_'.$i.'_'.$subfield;
    $images[] = intval(get_post_meta($post_id, $field, true));
  }
  if (count($images)) {
    // convert to comma separated list
    $images = implode(',' $images);
  } else {
    $images = '';
  }
  update_post_meta($post_id, '_product_image_gallery', $images);
}
