I don't think it is a good idea. It would be one of those gimmicks like falling off an edge in an adventure game. Clearly, you would not have done that if you were actually walking on that thin plank to the next level. The game mechanics and the fact that you cannot see your own feet or hold your hands out to balance is why you fell.
In RS, as with any video game, your spatial awareness within the game will never be as good as outside the game. For example, in order to increase player awareness of grenades, RO2 makes a sound (most of the time) when the grenade lands, and often the character will call a grenade out, regardless of actually looking at it.
TWI increases your awareness of barbed wire by making it non lethal. In real life, it would be pretty obvious when encountering barbed wire, and you'd take the necessary action to avoid it (blow it up, go around, jump over, etc.).
