I don't think it is necessary to do that. As an experiment, you could
try extracting a single message from your archive.mbx (into say
msg.txt) and then do

bin/inject --listname=<listname> --queue=news msg.txt

The problem here is that AFAIK there's nothing in Mailman you can use
directly to 'parse' the mbx file. There's a Mailbox class which is
essentially the standard Python mailbox.PortableUnixMailbox class
which has a next() method to get the messages one by one, but no
direct command (other than bin/arch) that processes mailbox files.

Assuming the experiment above works, you could probably create a simple
script in Python (or perl or even a shell script) that would extract
the messages one by one from the mailbox and pipe them to

bin/inject --listname=<listname> --queue=news

(bin/inject reads stdin if no filename arg is given).
