Sure you can do this.

Or do you want to know how?

1.) get gnupg software.
Install it, generate your keys and your revocation certificate (you
never know when you will need ont.
2.) Upload your public key to a keyserver.
3, Have A, and C do the same.
3a.) If you want to anytime, have B and D do it too.
4.) When you want to send data get the public keys for A and C.
5.) Encrypt these data with the public the public keys of A and C.

Am I missing something?
