Yes that would work though you'd need to export from the authoring tool, make your edits then re-import the amended content. So you'd need to be using a version of the authoring tool that supports course import (v0.5.0 or better).

I would have thought it would be quicker to build the structure of a course in the framework though; either by copying an existing course as a 'template' or by using tools like adapt-setup and csveat
