Is it possible to turn this into a Sandbox solution for SP13?

This is not possible since it uses a HttpModule which can only be deployed via Farm Solution. If you're limited to Sandbox Solutions your best option is to implement AllowFraming on the page or master page, but that's limited to SharePoint pages.
