If y'all are talking conversations, I can help … having recently refactored my conversations plugin.
You can check out an example post with webmentions bounced over from Twitter by Brid.gy here
Or see how @sod made the cards wicked cool here

All my visible HTML is element producing plugins are built to be callable from custom themes (like my own). I check for the partial and call it when it exists. You can do the same check (how I imagined this stuff would eventually work) … or cannibalize anything you see that you like. Whatevs.
Update: of course, the README is out of date … the data directory plus the sass file tells the story.
