metaclass that inherits a class of that metaclass?

[ironfroggy]

Hoping this isn't seeming too confusing, but I need to create a
metaclass and a class using that metaclass, such that one of the bases
of the metaclass is the class created with that metaclass. I can't
figure out a way to do this, even after trying to add the class as a
base after the classes have been created.

Is there some way I can get this to work properly?
