Change class parent dynamically from attributes python 3

I want the new class to dynamically inherit from different parents depending on an attribute given when creating an instance. So far I've tried something like this:

class Meta(type):
    chooser = None
    def __call__(cls, *args, **kwars):
        if kwargs['thingy'] == 'option':
            Meta.choose = option
        return super().__call__(*args, **kwargs)

    def __new__(cls, name, parents, attrs):
        if Meta.choose == option:
            bases = (parent1)
        return super().__new__(cls, name, parents, attrs)

It doesn't work, is there a way that, depending on one of the parameters of the instance, I can dynamically choose a parent for the class?
