Changing the format of the munged From: header would require changes to
the code in Mailman/Handlers/CookHeaders.py. There's no way to do this
with list configuration settings.

The only other thing you could do is not apply DMARC mitigations to the
From: header and set your list to not make DKIM breaking transformations
to the message. See item 2) at <https://wiki.list.org/x/17891458>.
