You can't do an exact copy, but i believe you can install Wordpress and transfer all your posts and images to that.
Ya Similar reply, What we can do is maintaining same url structure and post so that you don't use traffic. But off course theme and other things would change.
See open your Wordpress admin panel go to tool go to import select blogger to import open your blogger panel, accept authorisation, and transfer. I must recommended a professional help but at least you must give a try urself...
