Upgrading the popfiles downloads section for MvM could be useful. Maybe putting a more integrated link to the map it was made for (assuming it has a page on tf2m), and maybe even the map page has a section with a list of custom missions associated with it.
It might also encourage the scattered mvm community to have a more centralized place to share content.
