Apologies, I updated it.

class MyModelAdmin(ModelAdmin):
    model = MyModel
    form = MyForm
    def get_form(self, request, obj=None, **kwargs):
        form_class = super(MyModelAdmin, self).get_form(request, obj=obj, 
        some_parameter_for_one_thing = 
        from django.forms.models import ModelFormMetaclass
        class FormMetaclass(ModelFormMetaclass):
            def __new__(mcs, name, bases, attrs):
                attrs["some_parameter_for_one_thing"] = 
                return super(FormMetaclass, mcs).__new__(mcs, name, bases, 
        import six
        class FormWrapper(six.with_metaclass(FormMetaclass, form_class)):
            def __init__(self, *args, **kwargs):
                data = {"another_parameter_for_another_thing": 
                super(FormWrapper, self).__init__(data, *args, **kwargs)
        return FormWrapper
