Ouch-I guess I missed this little detail. I'm trying to get an idea of how 
best to do this.   Does this work? (easier in pcode than english):

if not msg.is_multipart and msg_type=="text/plain":
	bod=msg.get_payload()
	<do transform on bod>
	msg.set_payload(bod)
elif msg.get_type() == 'multipart/mixed':
	for part in msg.walk()
		if part_type == "text/plain":
			bod=part.get_payload()
			<do transform on bod>
			part.set_payload(bod)

I've sort of cobbled this together on the fly here, so if it's totally off 
please forgive my ignorance, stupidity, lack of sleep, etc...
