No video.js doesn't support that. If you really want it to happen you could build it with the fullscreen API.
You can add this plugin, which enables double click and some other hotkeys with mouse and keyboard:

In my opinion, this approach - using plugins for extra functionality - is very well. Because code base should be tiny as much as possible :))
