This has been discussed in alt.security.pgp. Yes, it can be easily
implemented and indeed in the way proposed by you. Version 2.2 of PGP
will have this feature. The only problem will be that such "multiple
encrypted" messages will not be readable by older versions of PGP
(just like a clearsig message is not verifiable with PGP 2.0).
