As I said in the thread of 'which other characters you want for the Mythos line', Luke would be a great Mythos character if the statue is inspired to that moment in EPVI when he is alone in a cave, bulding his own lightsaber. It's a scene that has been deleted from most releases and it's a great scene, very evocative. Remember that the Mythos line explores the characters so Luke HAS a Backstory: maybe not in EPIV, but between EPV and EPVI he has done a lot of things too.
Anyway, I agree with you on Nihilus, Sion, Traya, Revan and the KOTOR characters.
I have no idea why he didn't put that scene back in after all the crap he's put in the movies. It was one of very few real "Jedi" moments in the OT.
The thing with the mythos line is that it's gaps that are untold story's, left to our imagination. A mature aged Luke pondering his past would be cool. I mean who say's the mythos has to come from the past. Why not the future?
