I have made this working by creating one View where model is basetype and then register this view in a InitializableModule that implements IViewTemplateModelRegistrator.

public void Register(TemplateModelCollection viewTemplateModelRegistrator)
        {
            viewTemplateModelRegistrator.Add(typeof(ContentBasePage),
                new EPiServer.DataAbstraction.TemplateModel()
                {
                    Name = "PageTeaser",
                    Description = "Displays a teaser of a page.",
                    Path = "~/Views/Shared/_PageTeaser.cshtml",
                    Inherited = true
                }
            );
        }

Thanks Mari, I've just got this way working myself as well using the EpiServer MVC template as an example. I love this approach because of the ability to pass tags in so you can control which is used. I'll mark this as accepted as this is the best approach I've found
