Suggestions?

How about some kind of dual pass in your given scenario?  First sign the
plain text to provide the authentication - then encypt the signed output
as an entity on it's own. Bob the stockbroker can then decrypt the order
and store the signed text.

Any use?

This is what I have been advocating for quite awhile now and how I have my
current PGP implementations working.

IMHO signature retention is more important than any advantages of a "one
pass" operation.
