Can I do this with the Duplicator Plugin?

Ok, so here’s what happened and why I’m asking this question… I was changing simple things on a friend’s e-commerce site & we ended up updating the WP version. No backup was performed and this caused a break in the Shopp plugin that was installed. Shopp was not helpful, so I thought maybe I could use the Duplicator plugin to clone the site, then install the clone on my domain, then install woocommerce over top of Shopp and then remove Shopp. Then I’d like to install the Duplicator plugin on my domain and clone the site so that I can move it back to my friend’s original domain.

Any thoughts on if this might work OR if it wouldn’t work as described, does anyone think there’s a way that it could work? There are just under 200 products, with descriptions & pictures + the goal is also to go with just PayPal, as opposed to using one of those pricey credit card processors.

If this scenario is just too “out there” I should be able to export the products from my friend’s site & then import them into something like a wp esell template on my domain, but would there be any way of exporting a “copy” instead of the permanence of exporting the original product info., so that I’m not disturbing the the site to where pieces or all are gone while this is all taking place. I’m trying to make the changes as seamlessly as possible, as opposed to the original (my friend’s) site functions being crippled by my tinkering. Any help would be much appreciated. Thank you for taking time to read this.
