E-commerce removal and localization issue

Hello, I am having an issue with a project for a client.

Here is a quick (as possible) summary.

I purchased a template with e-commerce functionality (which the client, requested).
In the end the client doesn’t want the e-shop (for now) but want’s to add localization to the site.
The project has been hosted in an e-commerce plan so I can’t add a localization plan to it.

What are my options? As far as I know e-commerce can’t be removed and duplicating the site piece by piece is also an issue due to the template (and the amount of work involved).

Is there some way I can add localization to the site while excluding it’s e-commerce features. (i.e keep them “un-translated” since they will not be used either way)

EDIT: Forgot to mention. In the case of hosting the e-commerce site as a CMS site, I will not be able to whitelabel it. Is that correct? Because this is also an issue.
