Thanks for the insights! I'll carry on with this and see what I can make happen.
I'm not able to introduce a factory pattern at the point Region object is created without monkeypatching an external library. However, I'm now going to explore instrumenting that class using mapper() instead of having separate ORM objects. Thanks, as always, for maintaining SQLAlchemy so well and for so long.
