Duplicate current quote with new ID on Magento 2

Question

Is there a way to somehow take the existing quote and create a new one identical to it but with a new ID?

This is what I currently have:

Updated following suggestions from @Vishwas:

use Magento\Framework\App\Action\Context;
use Magento\Framework\Controller\ResultFactory;
use Magento\Store\Model\StoreManagerInterface;
use Magento\Quote\Model\QuoteRepository;
use Magento\Framework\Mail\Template\TransportBuilder;
use Magento\Framework\Translate\Inline\StateInterface;
use Magento\Checkout\Model\Cart;
use Magento\Catalog\Model\ProductFactory;

class ShareCart extends \Magento\Framework\App\Action\Action
{
    protected $resultFactory;
    protected $storeManager;
    protected $quoteFactory;
    protected $transportBuilder;
    protected $stateInterface;
    protected $cart;
    protected $productFactory;

    public function __construct(
        Context $context,
        ResultFactory $resultFactory,
        StoreManagerInterface $storeManager,
        QuoteRepository $quoteFactory,
        TransportBuilder $transportBuilder,
        StateInterface $stateInterface,
        Cart $cart,
        ProductFactory $productFactory
    ) {
        $this->resultFactory = $resultFactory;
        $this->storeManager = $storeManager;
        $this->quoteFactory = $quoteFactory;
        $this->transportBuilder = $transportBuilder;
        $this->stateInterface = $stateInterface;
        $this->cart = $cart;
        $this->productFactory = $productFactory;

        parent::__construct($context);
    }
    public function execute()
    {
        try
        {
            $post = (array) $this->getRequest()->getPost();

            $id = $this->cart->getQuote()->getId();

            if ($id > 0) {
                $quote = $this->quoteFactory->get($id);
                $items = $quote->getAllVisibleItems();

                foreach ($items as $item) {
                    $productId = $item->getProductId();
                    $_product = $this->productFactory->create()->load($productId);

                    $options = $item->getProduct()->getTypeInstance(true)->getOrderOptions($item->getProduct());

                    $info = $options['info_buyRequest'];
                    $request1 = new \Magento\Framework\DataObject();
                    $request1->setData($info);

                    $this->cart->addProduct($_product, $request1);
                }
                $this->cart->save();

                // Retrieve form data
                $email   = $post['basketshare-email'];
                $message = $post['basketshare-message'];

                $from_name = "";
        }
    } catch (\Exception $e) {
        $this->messageManager->addError(__($e->getMessage()));
    }
}

}

UPDATE:

    $this->cart->addProduct($product, $request);

}

// save the updated cart items then re-attach the cart to the original quote
$this->cart->save();
$this->cart->setQuote($quote);
$this->checkoutSession->setQuoteId($quote->getId());
$this->cart->save();

I think there is something I'm not doing right here but I'm struggling to find any help on Google at the moment :)

All you need to do is to paste below code in controller action that you are executing for copying quote and copy one quote with all product items into another.

<?php
use Magento\Framework\App\Action\Context;
use Magento\Framework\View\Result\PageFactory;
use Magento\Quote\Model\QuoteFactory;
use Magento\Checkout\Model\Cart;
use Magento\Catalog\Model\ProductFactory;
class Copyquote extends \Magento\Framework\App\Action\Action
{
    protected $_resultPageFactory;
    protected $quoteFactory;
    protected $formKey;
    protected $cart;
    protected $product;
    public function __construct(
        Context $context,
        PageFactory $resultPageFactory,
        QuoteFactory $quoteFactory,
        Cart $cart,
        ProductFactory $product
    ) {
        $this->_resultPageFactory = $resultPageFactory;
        $this->quoteFactory = $quoteFactory;
        $this->cart = $cart;
        $this->product = $product;
        parent::__construct($context);
    }
    public function execute()
    {
        try
        {
            $id = 'YOUR QUOTE ID';
            if ($id > 0) {
                $quote = $this->quoteFactory->create()->load($id);
                $items = $quote->getAllVisibleItems();

                foreach ($items as $item) {
                    $productId = $item->getProductId();
                    $_product = $this->product->create()->load($productId);

                    $options = $item->getProduct()->getTypeInstance(true)->getOrderOptions($item->getProduct());

                    $info = $options['info_buyRequest'];
                    $request1 = new \Magento\Framework\DataObject();
                    $request1->setData($info);

                    $this->cart->addProduct($_product, $request1);
                }
                $this->cart->save();
            }
        } catch (\Exception $e) {
            $this->messageManager->addError(__($e->getMessage()));
        }
    }
}

Now you can use or customize this code according to your need of copying one quote to another one in your Magento store
