The alternative would seem to involve several tens or hundreds of passes 
through the file, or to write a standalone post-processor I suppose. Any way to 
submit a patch or write a hook to do this in the same pass? The rub would seem 
to be making it dependent on the multicast address change.

you can change/hardcode a new MAC, but there's no way of recalculating
based on the IP address.
