Use element to create mega menu?

I'd like to do a mega hamburger menu, but I'd rather not have one more plugin on the site. I saw the simple mega menu topic using CSS, which is fine, but I was wondering... is it possible to create a mega menu using an element? I saw this post on creating a hook using a shortcode – theoretically could I put this shortcode inside a menu sub item, and then hook an element inside? Just trying to think outside the box a little on this one!
