Sure, set it in Greyhawk or the Realms. A short sidebar for other settings would be nice, along the lines of "In Greyhawk, set this adventure _____ with these changes; In the Forgotten Realms, ______; In Kalamar, ____", etc. The notes could be fairly short -- location, name changes to key towns, citites, or groups, and perhaps which deities to use for NPCs. That way, we all have a known point to shift from.
