You can already replace and tweak the fields in a way similar to what you
are proposing. For example, you can create a Form or ModelForm, and in the
__init__() you can do:
def __init__(self, *args, **kwargs):
super(MyForm, self).__init__(*args, **kwargs)
self.fields['title'] = models.Charfield(max_length=30, required=False)
