I am not an expert here. But I have same Theme.
What I tried is: I have created static Home page in WP and copied “text” (code) from each section I want to “text” of the Home page. I also had to create the Headings for each section.
That worked pretty well.
The only think is I have Master Slider plugin for my header sliders as I use deferent one on deferent page and I think this Plugin is very good.
This may work for you too.
BTW did you worked out how to change colour of text on Read More buttons section 3?
