Would it be theoretically possible to create a 'vibration module' for the Deck?

As mainly a console gamer over the years, I've become quite used to playing with a controller that has vibration. I feel that this is one thing the Deck is missing out on.

So I'm wondering if it's possible to somehow connect up a small vibration motor (externally) that can be connected to the Deck, and have it recognised as a controller?

Possibly more effort than it's worth but would be interesting to see if anyone has any ideas.
