Yes, we currently use that approach.
For instance, we have live-streamed conferences with multiple video sessions. I’d like to display them in our community on a Page that is nicely branded. Then as they want to discuss a session, provide a link so they can click over to the discussion for that session.
This enables our Discourse community to be a one-stop shop for everything related to an online conference: secure permissioning of the content, viewing the content on a branded page, and discussing the content.
