Add custom page template on Sparkling

Hi!! Thank you for very beautiful themes!!!
I need you to figure out my issue!!
I’d like to use Sparkling for my website but I’d like to use travelify “template-blog-medium-image” to choose during create page.
How can I add this page template (template-blog-medium-image) in Sparkling?

It is not possible with current theme and you can’t just take template from one theme and move it to another. You have to rewrite the entire thing to make it work from one theme to another.

The easiest solution here is to use theme which is between these two - Dazzling.
