From what I saw, there's no easy way to download a remote template.
You'd need to use EACH template in a local template (meaning, if there are 60 templates, you'll need to create 60 local templates and import each of the remote templates), and then export them all.
Alternative: We group buy an unlimited license and each one uses the license on its own website. Not sure if it could get caught. Also, we would need the automatic.css license. That could potentially bring the price very high, but if we group 10-20 people, it'll be very cheap.
Prices:
Automatic.css: 149/year for 100 websites
Frames: 299 lifetime, unlimited websites.
Total: 448 for the first year, then 149
10 people, 44.80 first year, then 14.90
20 people, 22.40 first year, then 7.45
