Well... Honestly, as for long term, I actually proposed that Vereesa should rather die in the possible future elven civil war, and I had a reason for that - I was thinking about High Elves withdrawing from the war at some point, cause that would for sure be huge help in further differentiating them from Void Elves, and Vereesa is someone who would never agreed for such thing.
But there is also no reason to give tattoos and ranger look to Silver Covenant. They are military organization from Dalaran, specific faction. They don't have to be main source of playable HIgh Elven population as allied race, and even shouldn't be - as allied races require recruiting scenario. Situation could be here similar than with Dark Irons, where part of them was recruited earlier, and part of them is brought now. Old Ranger look fits more for Highvale elves, and so - them, or other similar rediscovered groups of exiles would be recruited population, while Silver Covenant getting some role in that scenario.
I was recently looking on updated minimaps of Eastern Kingdoms, on all that empty mountains south of Quel'Thalas... There could be in fact plenty added things, much more that it would be needed here.
Even if we wouldn't consider here elven civil war, and death of Vereesa, she is still first of all commander of city dwelling militia group, and so - her appearance should stay coherent with function, if she ever got new model. Just as Alleria's look stayed old styled during Legion, even if there are no elves presented in that way anymore.
I absolutely fully support this.
However, I would suggest myself a black eyes. Believe me - there is nothing giving better dark-elf vibe, than chalky white skin with whole eyes going black.
