    I think I understand the answer to my question... First is that there is
    more to having a secure email conversation than using a public/private key
    encryption. The second is that the key pair has a mathematical relationship
    that I cannot replace the private key since it would violate the
    relationship and not work.

    Thanks to everyone answering my question.

    Hey Tony,

    The reason is because ONLY Alice's private key can decrypt something
    encrypted by Alice's public key, and vice versa, only her public key can
    decrypt something encrypted by her private key. For this reason you
    can't make an arbitrary pair and say they are a key set.
