Though I solved my own problem through some means, no - your
suggestion would not work. The reason is that the TestCase.__call__
code does: _pre_setup, set client, super...(), _post_setup.
The only way to hook into that code would be to mash up the MRO for
TestCase and inject oneself into the super call. And then re-instatiate.

A rather common idiom I've seen is:
class TestCase(...):
client_class = DjangoTestClientThing
def __call__(self, ...):
# ...
if self.client_class:
self.client = self.client_class(...)
# ...
Essentially achieving the same as you, only because of Python's name
resolution machinery, you could also do `my_inst.client_class = Blah`
to specialize per instance.
