Create direct registration link to a template created with new blog templates

Ok so the thing is this, i have a wordpress theme with a drag and drop sistem and i have created around 20 demo homepages from which i want to create different blog templates.

What i want to achieve is the following:

I will list all the templates with help of images on the homepage, i would like that when an user click on one of them he will be taken to the registration page with that template already choosed.

Is this possible?
