No. ...and so I also don't want dismemberment of oppenents either.
I want dismemberment as long as it's pretty rare and depending on weapon, never with dagger sometimes with a waraxe, and heads is a so rare event you take it with you home,
Yes missing a limb would be fair, an enemy cut of your hand and you can not find it

However this would permanently gimp your character as a I guess it will not grow back. More so if you are a master in two hands weapon.
