Yes it would be a editable view where you can also manipulate and save the data.
I think cloning a page is also a good option but can also has its flaws when not done right. There is a plugin where you can copy pages and files etc. Page/folder/file copy plugin via a widget. But I don’t belief my client would be able to understand how to enter the right path and destination and I also don’t feel comfortable with that solution. It’s a too complicated imo.
Copy and pasting on the other hand would be something that we are very familiar with which makes it more likely to be used without the fear of doing something wrong or unwanted. There is just no “revert” or “undo” for your actions.
I would love a cloning or copy page feature. But the process of doing that should be very simple and thought out.
