I think you did not get the point about QMetaType and QMetaObject. They

I don't think that they can.
1) mark the constructors in the classes you want to be able to construct
from your file as Q_INVOKABLE
2) register the types in the meta object system
The meta *object* system has no registration.
The meta *type* system requires that the registered type be default-
constructible and copyable, but QObject is not copyable. Therefore, QObject-
derived classes cannot be registered with the meta type system.
Am I completely misinterpretting the documentation then?
http://doc.qt.io/qt-5/qmetatype.html#metaObject
If I read that correctly, you can register a
pointer-to-a-QObject-derived-class-instance and use that. So, indeed,
you do not register the type, but the type*. And that has no problems
with being default constructed or copied.
I have not tried this at home, so to speak. Perhaps I should.
