I think that for your homepage instead of trying to build a slider to replace your current layout, you should replace your background picture with a gif. That way the gif will act as a slider and you will achieve the same effect with the least amount of work. You can create a gif file following this tutorial How to make an Animated GIF in Photoshop - YouTube I hope this helps you.
Remove the current image background.
In the home section place a Slider from the Elements panel.
Add as many slides as you need and give each slide it’s own bg image.
You can hide the arrows and nav dots and set slides to change automatically.
Here’s some info about sliders.
