django-polymorphic inline admin with many to many relation

Question

Is it possible for a model with many to many relation to a polymorphic model to display stacked inline forms (depending on the type of the child model) ?

Using the example from the django-polymorphic docs i'm trying to make the list of ModelA models to display as admin.StackedInline in the RelatingModel admin page, each with it's specific form.

First, you need to define your inline class base on your related model

class MyMode1lInline(admin.TabularInline):
    model = MyModel1
    extra = 1

Now you need to connect your inline to the PolymorphicChildModelAdmin

polymorphic_models = (MyModel1, MyModel2, MyModel3)
for child in polymorphic_models:
    @admin.register(child)
    class PolymorphicChildModelAdmin2(PolymorphicChildModelAdmin):
        if child == MyModel1:
            inlines = [MyMode1lInline]
        base_model = child
        show_in_index = False
