how to dynamically instantiate an object inheriting from several classes?

I have a function that takes a reference to a class, and then
instantiates that class (and then does several other things with the
new instance). This is easy enough:
item = cls(self, **itemArgs)
where "cls" is the class reference, and itemArgs is obviously a set of
keyword arguments for its __init__ method.
But now I want to generalize this to handle a set of mix-in classes.
Normally you use mixins by creating a class that derives from two or
more other classes, and then instantiate that custom class. But in my
situation, I don't know ahead of time which mixins might be used and
in what combination. So I'd like to take a list of class references,
and instantiate an object that derives from all of them, dynamically.
Is this possible? If so, how?
