Can you be more specific? This model you have uploaded a picture of is a model that originated from Warcraft III. In this case, World of Warcraft (a 2005 game) basically used the same asset from Warcraft III (a 2003 game) for the character -- but with a few slight minor modifications.
So, it is very unclear if you are a Reforged/WoW player who does not know that you are uploading a picture of the Warcraft III unit models that existed for the last 20 years, or if maybe you are a player who knows everything I just said and wants a very specific skin-color on the existing Warcraft III models for what Warcraft III refers to as the "Draenei" (use of this name in Warcraft III predates the World of Warcraft race by the same name, which was a retcon circa 2007 included with the Burning Crusade. Until the Burning Crusade released with the storyline retcon to add blue goats to the alliance, the word "Draenei" in the Warcraft III universe referred to the creature you have uploaded a picture of).
Here is a picture of the models already included in my Reforged installation. As you can see, the models for the "Reforged" version of these guys are heavily modified from the original lower resolution versions from the 2003 game (shown in the back row). Reforged changes how these characters look to be more in line with the WoW storyline changes.
None of these models are imported. To create this picture, I opened the World Editor and placed the built-in units on the ground using the built-in models:

So, are you asking for someone to modify the Reforged themed assets (bottom row) to stylistically match the original Warcraft III Draenei assets (top row) ?
Or are you a non-Reforged player who wants a modified form of the original Warcraft III Frozen Throne 2003 game assets that would have the same armor as the WoW model?
Because WoW and Warcraft 3 were developing in parallel, the portrait file for the Warcraft III draenei from 2003 matches the WoW 2005 model and has the necklace in your picture, so adding it to the ingame non-portrait model on Warcraft III would be super easy to do without even requiring a custom texture.
