Dúnedain here, just wanting to fix the misconception.
In Shadow and Flame we used meshes from ROTK yes, but none of those models are being used in Age of the Ring. Aragorn specifically I made with the intention of not having assets from Return of the King and, looks better because of it if I do say so myself.
Anyways, no need to derail the topic anymore. Legolas's head is too small for his body on the Fellowship version but otherwise not bad.
