Scenario with my own characters

I once saw Tom Kuhlmann demonstrate how to replace the scenario character with custom characters. The trick is to publish the course, and then replace each character PNG in the assets folder with a custom-character PNG. The new images must use the exact names as the original assets. 

A scenario block can use a different character in each scene. But it doesn't allow more than one character in the same scene.
