An example I have in mind is like when a nephalem gives the human all his powers,
Similar to // Solo Leveling SPOILER
The Shadow Monarch gives Sung Jin Woo all his Powers
The physiology itself I think not, but the powers, maybe (but that wouldn't turn the human into a nephalem, but a Transcendent Human)
If the human was Half Nephilim and Half Cambion!
I don't think so unless you make settings specifically fitting for this.
Maybe giving their blood or soul to the human in question novels use that concept with dragon or werewolf giving blood to a human to change their (human) physiology.
I would like to believe that since humans can make either good and bad choices, it should be possible for said person to access both holy/unholy abilities
What do you think?
