Thanks for getting back to me about this. I ended up, for the moment just choosing to go for Composition over Inheritance, I appreciate that its not really a best practice in this scenario and isn't the 'proper' way to achieve it but it works for me.
I now just create an instance of the dbus object in my class init proceedure and have a getRealObject() method which returns the composed dbus object for any calls I need to make on the bus.
