I don't know. I'm no SA expert, but I've worked with DMARC mitigation code and would assume that a RFC-2822 compliant understanding of the From address would be the first step.
More caffeine and a little more Googling, I think that SpamAssassin already has sufficient knowledge of RFC 2822 (obsoleted by 5322) with the From:name and From:addr
My understanding is that From:name is the human friendly name and that From:addr is the email address.
So, I think that SpamAssassin already knows enough RFC 2822 (5322) to deal with this.
Mailman's DMARC mitigation code uses something very similar to "name at domain via" <list@listdomain> which retains all the information from the original From address while providing a functional From address using a domain name which passes SPF, a sufficient condition for passing DMARC.
