Specific templates based on products' sizes

Here's the idea: to add specific templates based on the products sizes.

For example: the print on a XS will be way smaller than the one on a 3XL.
What I think would be useful is the possibility (if the site's owner wants to) to diversify the template size based on which product size is the customer.

This way, the customer will always have a real life looking mockup under their eyes.
