I think you could take the original Darth Revanīs robes and remove the cape and the skirts of the trousers, or leave a part for the front and back skirts (somethink as Darth Malakīs robes instead of Darth Revanīs), and reskinning it in dark brown or light grey, removing the shinning thing of the pantaloons and the boots, and making them more like a robe or a light armor, slightly nicer. And its stats: +4 to strength, +2 to charisma, +1 to regeneration, +5 to defense, any restrictions about side force, ... Something you wanted.
Humm! The truth is that already I am not so sure of it.
I donīt use Darth Revanīs robes because I think theyīre awful (I prefer a Jedi robes mod); but it seemed to me theyīre quite better in the screens, quite cool.
But now ...
It is up to you, you decide.
