Set a parent page for author’s archive in WordPress

I want to make a page /authors with authors list and set it as a parent for author’s archive (author.php). URL should look like authors/jonhsmith with breadcrumbs “Authors -> John Smith”.
Is it possible using default author.php without creating custom post type?

I’ve created “Authors” page with slug “authors”. Changed author page slug from “author” to “authors” with Edit Author Slug plugin.
