This is more of a question. Is it possible on the homepage to show post title, featured image and maybe a tagline? Or can it only be an excerpt?
The posts featured image, title and excerpt are shown on the homepage.You can also set that the post content is used instead of an excerpt i.e. appearance \ customize - blog - display content or excerpt in standard blog.
Hope this answers you question.By the way the demo site is here http://fox.withemes.com/ if you want to take a look.
