That really sounds like something that I would tackle with Procmail or a 
specially written filter (Perl or Python).

1)  Extract and save the From:.
2)  Remove all To: / From: / CC: headers
3)  Add a new To: set to the list.
4)  Add a new Sender: set to the saved From:.

Aside:  I'd likely also remove other headers that tend to break things, 
like DKIM* / Authentication* / et al.
