I'm going to be interested in something like this myself when I upgrade with the next model later this year. I used to use bedside docks with Lightning and with those, having enough weight to the base so it would stay down was critical, or it'd pull up off the nightstand with the iPhone as I'd try to remove it. I imagine the same thing will hold true with MagSafe stands. Here are a couple I found right off the bat that "should" do the trick. They tout having a heavy base for just this reason.
