I can't say that I'm a true expert, or that I've really investigated,
but I believe you can wrap an entire message (with multiple parts) into
a single part of the wrapper message.  I don't think you need any new
message-structure standards.  You might need standards for headers that
would say that that's what you've done, and you certainly would need MUA
support.

(And to others who have replied:  yes, all understood.  Like I said,
adoption would be hard.)
