I would not. I think the void elven customization should focus on them being void elves, and draw to that. Rather than try to change them into another race completely.
That is awfully condescending. When you take a step back and read what you write, how do you seem to yourself? To me you seem a little like a child told he doesn’t need a candy bar and is shouting at his mum in the isle.
Those are different though. 1 is adding a unique customization option that isn’t already present. The other would be making a core race of a faction now available to the other faction through a cosmetic option.
The alliance have night elfs, but not undead night elfs or dark rangers. They have dwarves, but not undead dwarves. They also wouldn’t be going against their lore by saying “hey, im a night elf. I just look undead”. They would literally be undead and a new race.
The horde has blood elfs. An untainted void elf = blood elf 100%. There is no comparison for the suggestions you gave.
I am all for options when its plausible and makes sense. In this case though, it doesn’t due to clashing with an established race as well as destroying the lore and identity of what it means to be a void elf.
Great but see he said a different race, they are the same race, as well as in the current lore they cant even recreate it, valeria and her teacher could so in turn they could make more void elfs but they’d look more like valeria or how they normally look. See the issue.
They would look undead but with like, golden eyes. I wouldn’t, but lore would be like “where did all these high elves suddenly come from”. They would have to be from a time prior to the name change and you all would have to have some lore reason that suddenly, ancient corpses are all being risen from the dead.
The full spectrum of human skin tones for Blood Elves won’t even be an option until Shadowlands. Of course people were asking for what was available. If the Blood Elves had always had a full spectrum of human skin tones, I’m sure the High Elf request would have always included them.
