Well something like that depending on the Stripe infrastructure.

That currently happens when an issuer card is used in a merchant that is acquired/processed with the same issuing bank. It is called an "on us" transaction and doesn't need to fire through the card scheme rails.

I assume that still incurs a visa fee. Perhaps just bypasses the underwriting. Otherwise, I can't imagine visa would allow this.

I can't see how they could disallow it to be honest. That would be seriously anti-competitive.
