Hello Andrew,
Great question there. The podcast section in Epic (and our other church themes) is pretty tightly integrated into those themes both in functionality and in style. While it could be ported over, that would take a fair amount of coding to accomplish.
Here’s one option that wouldn’t require you to make any edits. You could use posts for each of your podcast episodes. You can group them together into series by assigning them to categories that correspond to each series.
Then create a new page that will serve as the landing page for all of your series. Here we’ll place the graphics for your series so that your visitors can click on the appropriate one and find the episodes that go with it.
Next you’ll want to create the images for your series. You’ll want to make them uniform in size so they line up nicely, say 300 pixels wide by 200 pixels or something similar.
Then it’s time to add them to your series page. As you add an image into a page in WordPress, you’re given an option to set what that image links to. Enter the URL for the corresponding category into the URL field and insert the image. Set it to align to the left so that other images can be placed next to it.
Repeat that for all the images and you’ll end up with a landing page for your series without having to edit things.
You can also add in a plugin like BluBrry PowerPress (https://wordpress.org/plugins/powerpress/) to handle the podcasting functionality for you; things like iTunes feeds and so on.
If you have questions implementing that just let me know. If you decide you want the complete podcasting setup from Epic or Kerygma, let me know and I can give you a quote on creating a child theme to add that in.
Thanks again,
Bill
