I doubt your parents would agree as it would probably be painful for your mother and even more painful for your father to send your brother back where he came from.

I have power of attorney for my parents so no need to bother them.

I doubt if your mother is physically capable of having your full grown brother being put back into her womb. Taking your words “send him back to where he came from” with a bit of perverse literalness.
