You can customize the formset used by inline for your B model, you can override a clean() method on it:

class InlineModelAdmin(BaseModelAdmin):
    ...
    formset = MyInlineFormSet
    ...

and

from django.forms.models import BaseInlineFormSet

class MyInlineFormSet(BaseInlineFormSet):

    def clean(self):
        super(MyInlineFormSet, self).clean()

        # Your custom validation. You can access all the forms via `self.forms`

Please refer to the docs and code:
