Inherit from other visuals?

I want to make a small change to an existing visual but I dont want to have to worry about maintainence. I know that I can place the link to the git repo in my package.json. Is it then possible to inherit from the visual and simply override a function? I would like it to look something like this 

class MyVisual extends OtherVisual {

   constructor(options: VisualConstructorOptions){
        super(options: VisualConstructorOptions);
    }

    public update(options){
        //my new code here
        super.update(options);
    }
}

Is it possible to do something like this? Any answer would be helpful!
