To be fair, it would have been a waste of a slot for VC. He wasn't that great, and has really no usable articulation below the waist.
Not to play conspiracy theorist about Revan being MIA, but....
...there have been a number of rumor circulating about the Benioff & Weiss series of movies. One that keeps recurring is that they might develop Knights Of The Old Republic into a film trilogy. Whether or not these rumors are true is unclear. Rian Johnson commented on the prospect of developing KOTOR into a film series and said that the story had already been told, so why do it again? But the rumors persist.
Is it possible that the figure got pulled because a KOTOR project may actually be in development for film or television? It's a thought.
