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.
