The fact that this will make the vanities permanently available makes a huge difference.
Putting a time restraint on the vanity helms will encourage players to rush to the level cap because once it is gone, you can never get one again. Like I said, people pay more for something that is limited. The devs know that. That's the whole point of the item being "elite."
When the item becomes permanent like you suggested, yes it gradually becomes harder to acquire, but you still can get it. HUGE DIFFERENCE. It takes away to the value and rarity of the item. Hence, people would eventually realize it really isn't worth paying.
In my opinion, it's all psychological. People value something rare or limited, and they will pay a lump-sum amount of money just to get their hands on it.
Though like I said, I like the idea in some way, but I just don't see it happening.
