Using Campaign Editor for multiplayer.

I have a question about an idea I just got. Would it be feasable or usefull at all to use the campaign editor to create a series of custom multiplayer maps? It is easy enough to make custom maps in Warcraft but as far as I know it is a pain to make a full-out mod or set up multiple different maps with your same custom gameplay. I haven't seen any example of a warcraft mod where you can easily adjust game-wide play, like a way to add aditional heroes or races to the regular melee game. But a lot of mods would require their own type of map anyway so even a way to easily update all the objects and triggers throughout a series of maps would be nice.

I suppose you might be able to do that, depending upon if it keeps campaign object data when exporting the map. However, this wouldn't do anything for triggers.
