I think this could be simplified a lot and many of the known issues addressed if this were narrowed to *only* resuming from drafts. message-mode draft files aren't MIME messages (or, at least, they're never multipart, and message-mode has its own special annotations over basic RFC 822), so rather than treating the draft as a MIME message and trying to transform it back into a message-mode-compatible draft (which, in full generality, would be somewhere between hard and impossible), what about just dumping the raw contents of the draft file into a buffer and pointing message-mode at it? If the draft file is available, you could even open it directly (this wouldn't work for remote usage, but remote drafts introduce many other problems, too).
