Can I take the header.php out of the parts folder in my theme?

I am using Woocommerce plugin with Stripe Payment Gateway, and it needs the get_header call to trigger the scripts. The Starkers theme only has a folder called ‘parts’ and the get_header gets called like this:
<?php Starkers_Utilities::get_template_parts( array( ‘parts/shared/html-header’, ‘parts/shared/header’ ) ); ?>

Question: Can I combine the header.php and html-header.php files and place them directly in the root folder so that I can use the get_header(); call?

Woothemes tech support says another option would be to add: do_action( ‘get_header’ );
But won’t that just call the header twice?

Many thanks in advance!
