Magento 2.1.3 Override – Rename Page-Wrapper Class in Empty.xml

I am creating a magento theme based on the magento/blank theme, and I am trying to change the opening div's class from page-wrapper to container.

Attempt
I tried to create a file in /app/code/myvendor/theme/Theme/view/layout/override/base/empty.xml with the intention it would replace the file in /app/code/Magento/Theme/view/base/page_layout/empty.xml allowing me to change the class but nothing happened.

        <container name="page.wrapper" as="page_wrapper" htmlTag="div" htmlClass="container">

                <container name="columns" htmlTag="div" htmlClass="columns">
                    <container name="main" label="Main Content Container" htmlTag="div" htmlClass="column main"/>
                </container>
            </container>
            <container name="page.bottom.container" as="page_bottom_container" label="Before Page Footer Container" after="main.content" htmlTag="div" htmlClass="page-bottom"/>
            <container name="before.body.end" as="before_body_end" after="-" label="Page Bottom"/>
        </container>
    </container>
</layout>

How can I achieve this? Thanks in advance!
