It's really not the same thing. Void Elves became the gateway for High Elves through customization. There is no easy way to implement High Elves as their own allied race at this point even if Blizzard was inclined to make yet another Thalassian elf allied race, which I just don't see them doing.
I believe that going forward, allied races will be more like the Vulpera, standing as their own thing and not just a spin off of an existing race. If you're taking the fact that we have Void Elves as some sort of indication that means there's a chance for High Elves as an allied race, I'm sorry to say but I think it's the exact opposite. The fact that Void Elves exist all but guarantees we won't get High Elves as their own allied race, and the customizations basically nailed the coffin shut. I'm not saying it's impossible, but the likelihood is so low considering all the above, I personally feel it best to devote my efforts towards making Void Elves able to fulfill the High Elf fantasy as well as they can.
The skin options were a big start. Some typical human hair colors along with a tentacle toggle alone would essentially complete the High Elf look. More hairstyles would just add to the variety. The "veneer" idea I mentioned before would allow Void Elves to completely fulfill the High Elf request, with only the Paladin class being unavailable. And frankly, I don't think the Paladin class is necessary for Alliance High Elves. Would it be a nice thing to have? Sure. Is it necessary to be a High Elf? Absolutely not.
But keep trying to fight for High Elves as an allied race. I wish you the best of luck because I'd play that allied race. I just don't see it actually happening though, so my energies will be devoted to the direction Blizzard seems to be going - Customizations to answer the calls for certain sub-races/splinter groups.
