I have a separate route that will generate a PDF of a page. This works well however I would like to generate a preview of the PDF for unpublished content.

Is there a way to do this by extending the umbraco Preview?

Alternitivly if I create a customer preview route for the PDF I have an issue getting an IPublishedContent of the draft/preview. If I get an IContent the issue is that all our code so far is based on IPublishedContent and does not seem and easy way to adapt IContent to IPublishedContent.
