They could literally add them, right now, without changing anything else, and it would be fine. Our character is, for all intents and purposes, a blank slate, with no prior history, and no age or anything.
You couldn't really do that with DHs or Evokers right now. The Hero classes are not blank slates, they have a backstory.
You can't just put a Goblin into the DH starting zone, because it wouldn't make any sense. Illidan, specifically trained Elves. They simply wouldn't be on Mardum.
Even more so with Evokers. Right now, it would make absolutely no sense. There would be no reason for a Goblin Evoker to be locked up.
And yeah, of course, Blizzard can do whatever they want, they could make a new scenario, however, the Hero classes actually need justification because most hero classes aren't just a thing that can be taught. Shamanism can be taught. Druidism can be taught. Paladins can be taught.
You can't really "teach" someone to be a Demon Hunter. You can't really "teach" someone to be an Evoker. You can't really "teach" someone to be a Death Knight.
