Local WOW servers

I’d love to see local hosting of World of Warcraft servers, that DMs can customize. let artists and writers create dungeons and items, let the items get graded (and coded),and potentially merged into the official game.

Would Blizzard lose money with this? They could still make each person pay $14 a month to join locally? is there a server cost the people chip in for?

New adventures. New dungeons. New items and weapons. New races and classes. Just like traditional role playing games.
