If you wish to believe so go ahead. One thing's for sure, the detachment of High Elves from Blood Elves. Since that is what the eye color denotes in particular to Thalassians where it matters. So no blue eyes for Blood Elves means they have no ownership over what occurs to the High Elves on Alliance.
Can you prove that blue eyes will be scoured to golden over time for them? Every official Blizzard developer response on Golden Eyes for Blood Elves is that the way they're handling it is keeping it to Paladin/Priest/Immensely devoted to Light elves. Hence that's why Blizzard continues to input green eyes onto Blood Elf NPCs.
If Blue eyes were meant to be scoured away they'd actually be showing a bit of that among the High Elves too, which they have not. Ion confirming the blue eyes are for NPCs, textures which were just recently added, goes against your notion.
If your hypothesis were true, they wouldn't keep creating new eye textures reinforcing the blue for High Elves.
So please provide evidence that High Elves will end up with Golden Eyes as well.
