I think the thread you linked to  says it is possible using
GnuPG's --show-session-key and --override-session-key options. And at
the end of the thread, Werner says PGP/MIME signs and encrypts using
separate MIME containers, which makes it easy to strip off the

I did. Gpg --list-packets output starts the same. But to get all of
the info on the two-step signed then encrypted, I have to run gpg
- --list-packets again on the signed but not encrypted file to get the
info about the signature.
I also tried pgpdump, which gives the same information for the one
step and the two step files. It appears to be a different (and
smaller) set of information than gpg --list-packets generates.
