Not a good idea. Have you ever noticed how a human opens a zipper? It's not just pull it down and presto! It's open. Nononononono... in case I wasn't 100% clear, I said no.
A zipper needs to have the slider handle pulled
up away from the zipper before being pulled down. There's a tiny catch in the slider that keeps the zipper from opening by itself at an inopportune moment (like the fly in your pants in public

). That catch is lifted away from the zipper teeth when you pull up on the handle. A garage door opener cannot provide that action. It might be able to close the zipper, but not open it. In a nutshell, you'd be stuck.
