Sure you can do this.

Or do you want to know how?

1.) get gnupg software. http://gnupg.org/
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?
