Django: How do I create a new model containing all the fields of another model (but unrelated to it)?

Given an existing Django model:

class MyModel(models.Model):
    field1 = ...
    field2 = ...
    ...
    fieldN = ...

I would like to create a wholly separate model that looks like this:

class MyModel2(models.Model):
    field1 = ...
    field2 = ...
    ...
    fieldN = ...

    fieldA = ...
    fieldB = ...
    ...
    fieldZ = ...

Multi-table inheritance does not work for me as I want MyModel2 to be backed by a database table containing all of its fields, not just the extra ones plus a link to the MyModel table.

Defining an Abstract Base Class might work if I could change the definition of MyModel. But is there another way, possibly using the Python type metaclass?

Why not an abstract base class for both, and one of your concrete classes has no further fields?
