That recent animated aging avatar by Sith Holocron made me think about the external signs of the age of the Jedi Masters in TSL.
The Council holorecord was from 10 years prior the game, but the members of the Council did not visually change (do they use the same models?). And obviously they could not be too young to begin with. Especially Vrook, he was same old man in the TSL (3951 BBY), in K1 (3956 BBY), in the holorecord (around 3960 BBY), in the comics "KOTOR" set shortly before the Mandalorian Wars (3964 BBY). He was even in the Council in the comics about Duron Qel-Droma (3993 BBY) and looked like he was already over 40 (this might just be an oversight, but funny in the context of this post).
In less than 10 years, Malak received tattoos, unique armor, skin changes due to the influence of DS, lost his jaw, replaced it with a metal plate, as a result received a new voice and, in the end, was killed. Revan shaved / grew facial hair all the time. But the members of the High Council didn't even change their hairstyles (let's assume that Atris had closet full of same white librarian' s robes).
This may be a reasonable idea for a mod or, perhaps, some kind of expansion to Full Jedi Council mod to visually reflect passing years on masters, for example, to make Atris and Lonna Vash younger in Holorecord and to age Vrook in the present time. Kavar and Zes-Kai Ell can be changed in any direction, I'm not sure about them (they appeared only in the background of one comic book).
What do you think about this subject? And is anyone willing to create such a mod if it fits the lore?
