You might want to take a look at how I built the FreePMProduct. 
The product contains several ZClasses.  
One example is an EMRClass (electronic medical record) it
subclasses OFS:Folder
Inside the EMR I can instantiate several of the other ZClasses.
Such as a Consult or an Address.
Some of those subclass Folder and some Document, depending on
it's actual use.
A change to one of these ZClasses cascades through all existing
instances.

Is that not what you are trying to do?
