Hopefully you’re familiar with html/css as this will take some effort on your end. Take a look in your home.php file and you’ll notice all of the home-feature-bg widgets use the same ID/Classes, so if you change one, you’re actually changing them all. So you would have to probably create your own css replacing the home-featured-bg…..and then add those ID/Classes inside the home.php file (which shows the homepage).
We can’t code it all for you (since that would go beyond the scope of support), but that should definitely lead you in the right direction. I had to do something similar a long time ago.
