Is it possible to get onebox URL previews with the URLS included in the post?

Yes. At least if using the RSS plugin. It will show the post with a message at the bottom
Doing a search for example I found out you can make a YouTube channel into an RSS feed link
Notice at the bottom of the pic there is:
This is a companion discussion topic for the original entry at https://www.youtube.com/watch?v=JH8Iyx4B5Kk
I also have setup an RSS feed from another Discourse forum I manage to the one above. I changed in that case a site setting to import full post. Without setting to fully import there is a smaller preview with option for the reader to expand the import or use the companion link to visit the site.
The Companion discussion link populates for the other forum.
