Duplicate configurable and childs products are not properly created

For a given feature I need to duplicate with very small modification existing configurable and childs products. This is what is doing this method.

The products configurable and ‘subscription’ childs, are created, but there are 2 issues remaining.

1 – It seems that the images are not properly added to the new products

2 – The link of the new configurable and the new childs of this configurable is not done; resulting in products being created but the configuration of color is not existing.

Here is the full code of the method. Thanks for assist

public function createSubscriptionMachineProduct(){
    $machines = $this->productCollectionFactory->create()
        ->addFieldToSelect('sku')
        ->addFieldToFilter('type_id', 'configurable')
        ->addFieldToFilter('status', Status::STATUS_ENABLED)
        ->addFieldToFilter('attribute_set_id', self::MACHINE_ATTRIBUTE_SET_ID);

    foreach ($machines as $machine){
        try {
            $originalConfigurableProduct = $this->productRepository->get($machine->getSku());
            $name = $originalConfigurableProduct->getName();
            $originalParentImages = $originalConfigurableProduct->getMediaGalleryImages();
