In Tokyo Ghoul Kaneki was converted into a half Ghoul when he was transplated
organs from a female Ghoul into his body. Can a person like him, who was
converted into half Ghoul by replacing parts of his organs, be reverted to
human by replacing those organs with human ones?

TL;DR Most likely not.

I will try to answer operating known facts, but description of ghouls biology
in Tokyo Ghoul is vague, so I can't avoid some speculation. I might also
accidentally drop spoilers of varying severity, so be cautious.

Kaneki has became half-ghoul after having kakuhou implanted. After this, he
obtained all abilities available for ghouls, including regenerative powers,
physical power, ability to use kagune etc. Which leads me to conclusion, that
in regards of organs, **the main difference between humans and ghouls is
kakuhou** (probably as main element to control RC cells, which are ensuring
the rest of ghoul abilities).

So, maybe, we can reverse half-ghoul state by removing kakuhou? Doubtfully. In
fight between Suzuya and half-ghoul twins Kuro and Shiro, Suzuya heavily
damages Shiros kakuhou, and later doctor Kanou mentions, that such damage to
kakuhou is lethal, and Shiro will be not able to recover (chapter 107 of Tokyo
Ghoul). Which leads me to second conclusion - most probably, **kakuhou
transplantation is irreversible**. This also makes sense in terms of RC cells
- after becoming half-ghoul, persons RC cells level in blood raises
significantly, and most probably, without kakuhou, excess of RC cells may lead
to [ROS](http://tokyoghoul.wikia.com/wiki/Rc_cell_over-secretion_disease)
development.

Also, one note in regards of transplanting human organs to ghoul. If ghoul
mother and human father will have a child, it was said that mothers body will
mistake child for food and consume it. I don't think that transplantation will
work in different way - most likely, human flash will be either consumed by
ghoul body, or will be populated by RC cells to ghouls level.

Most likely, to make ghoul a human, it would be better to try to decrease RC
cells level in their body, but it is not clear how it will affect ghouls
altered physiology. If I remember correctly, RC suppresants not just suppress
ghoul abilities, but also negatively affects their health.
