Best to hear Dave himself explain it.
I think some people have a much more rigid idea of what George's ideas are than even George does. You'd think the multiple editing changes to the OT would clue people in, but he's very flexible on the details.
In this instance it sounds like the initial idea was "let's try something cool", and because it's Mortis, you can kinda fudge it because you're not really supposed to know what's real, what's not, what's metaphor, and what's literal. For example; the show never reveals for sure whether that was really Qui-Gon (it probably was), or who was behind Ahsoka's vision (it was probably The Daughter), it only showed The Son behind Anakin's vision of Shmi.
So would they have literally been the still existent consciousnesses of Revan and Bane? Or would they have been merely echoes and shadows; a vision of those long gone, in a place where time has no meaning? I infer that the reason Lucas reconsidered was that on reflection, the implication cut too much against the grain of his ideas for how the force works.
This is totally normal and it's how any creative process works; writing, painting, drawing, designing, sculpting; all of it! You don't start with narrow parameters and restrict yourself to only colour within the lines, you start with a blank canvas and made broad bold strokes, then through successive drafts, iterations, and explorations it gets parred down and refined into something that works.
Of course they eventually revisit the idea by having Bane show up in the Yoda arc, but there it's made explicitly clear (and indeed, it's the point of the scene) that it's not really him. He's dead and gone. It's just an illusion.
ETA: Also bonus points for redesigning the character; I always hated the EU design for him (yes I know they put it in too as a statue, but you can barely see it and thus easily ignored.) I'll take
Ancient Chinese Warrior Balrog over
Bone-Face Nosferatu anytime.
Fenic was saved by Boba Fett via Mod Parlor and cybernetics. And she's been shot probably a day before given how slow Bantha seem to be.
Most of a day, certainly. Boba spotted the flairs from the fight when it was still dark, then she was shot literally at dawn, and it was dark again by the time he got there.
Of course how long or even consistent day lengths are on a planet with two suns is open to some interpretation. It could have been a very short day where just the one sun arc over the horizon and down again in just a few hours. Not that it matters much either way.
Yes, that was who I was thinking of. Super annoying foe in the battle too. That whole spinning attack was just aggravating.
There was also
this guy in Dark Empire who was basically a ball with a human head, which given what else goes on in those books is probably the least weird looking character of the bunch.
