I know nothing of the internals of ListProc, so I can't help directly,
No problem there -- ListProc I know, warts and all.
but there are a couple of Majordomo to Mailman conversion scripts (written in perl) in Mailman's contrib directory http://bazaar.launchpad.net/~mailman-coders/mailman/2.1/files/head:/contrib/ that might give you some ideas.

Archives can be imported to Mailman using Mailman's bin/arch tool, but the messages need to be in a *nix mbox format...
That should be no problem.
