Yes, that's possible. Though I am worried that it might also end up 
being a sub type of Offer, CreativeWork and Product, and that while 
there are perhaps ~10 properties that are needed for CourseOffering 
implementers will be presented with a list of ~100 to choose from. 
During the design phase, I would rather be agnostic about what are the 
parents of Course and CourseOffering, to draw properties we need from 
wherever in schema they currently are, and have a look at the end to see 
what they look like.
