Ghost HRT is just mind over matter.
Ghosts are made up out of the memories and feelings. Their bodies warp and change to reflect moods. (Edwins clothing reverts as soon as he's free of hell. Charles shirt gets darker the darker his mindstate is. Shelby twisting her features to appear scary.)
So.. if a ghost comes to the realization that they're trans, and they start feeling that they are a Man or a Woman, then their bodies change with that feeling. Features soften or sharpen, curves appear or disappear.
Non-binary ghosts change in between what they're feeling at the moment. Or they simply are blurry at the edges and refuse to conform to A Shape.
