this was the thing... I had the idea after watching the PT and thought about it...
The thing is, I actually like the idea more because how it would change the context of the conversation between Luke and Vader not so much that it fits the PT... But it was born from watching ROTS admittedly.
I always felt the good side of the force was more etherial and the dark side of the force was more material although they share attributes but that is just my take.
