Thanks for writing in! Regretfully there is no option or setting where you can easily swap the blog title and the featured image. This can only be possible with custom modification of the template. Because what you are trying to accomplish requires a template customization, we would highly to suggest that you use a child theme. This allows you to make code changes that won’t be overwritten when an X update is released. After your child theme is setup, please review how we recommend making template changes in Customization Best Practices.
After setting up the child theme, please provide us your site url or let us know what stack you are using so that we can provide a detailed and step by step process of doing the slight change.
Please let us know how it goes.
