I wanted to comment on this character (originally Eldreth) to show you that they can wear it even if they can’t personally complete the exalted grind. You just need to do it on one of the core races.
Well I don’t think they planned it that way. It’s just that the allied races have no coded allegiances so they can’t even start the grind. But weirdly only after you’ve done the intro dailies for couple of days, so you spend a minute looking at your screen in disbelief.
as Far as I know if you unlocked the Sunreaver one and faction changed that character to alliance, you’ll get the Silver covenant one instead of the sunreaver.
Sunreaver is basically the horde version of the Silvercovenant. You can’t get the Silver covenant unless alliance
That void elf hunter (Rhyleh) is my character so I’m positive it’s possible, you can mog a tabard to the silver covenant one after you’ve unlocked it with another (core) race.
