You are right that you can't just assign a pyqtSignal to an instance. It has to be a class attribute so that the metaclass can create the proper plumbing under the hood. Though i am not exactly sure what you need without seeing a bit more of the examples. Are they always QLineEdit widgets and is connecting the signal part of your builder? Multiple inheritance will solve the part about getting the signals onto the objects, but not really solving the connections if they are all different types.
