This has not happened, so it still counts.
As for your ideas about where to scrounge up extra High Elves.
The Silvermoon Rebellion: No. There is no issue threatening to divide the blood elves at present, and even if they did divide the 'new rebels' would have little incentive or cause to join the High Elves considering they've been happily Horde for the past seven years.
Outland Forces: A literal drop in the ocean. At most a hundred or two hundred individual High Elves would have come back. And where is the rule saying all of them went right back to the Alliance? It's conceivable a substantial chunk of the Elves would have converted to being Blood Elves once they realised that it was that or never set foot in Silvermoon again. Besides, how did the Elves in Outland cope with the addiction if not by consuming magic whereever they could. Like the Blood Elves did.
Even if every living High Elf gathered in one spot under one banner you'd still have only a few hundred individuals not strong enough to take control of their own destiny but reliant on patronage of a real power to protect them, such as Dalaran.
I'm obviously biased, but the evidence in favour of the anti-High Elf argument is clearly stronger both qualitatively and quantitively. If Blizzard ever do add High Elves as a playable race they are going to need a major ass pull to justify it.
