How to preview front-end of Checkout Sucess Page by order id

Question

I'm working on a module that styles the checkout success page. It's already done. I want to have a function preview in the back-end of my module that when you enter an order id and click preview, it will display the check out success page of that order in a pop-up or new tab.

Thanks!!
