Nice hack thanks!
However are you really suggesting that any non-bludgeoning damage injury roll on the Location and Effect table?
While that may be realistic it makes combat extremely dangerous and also seems at odds with the "Regain lost Health Points by spending the night in a safe spot." rule, which while common in game systems is definitely not realistic.
I think if I were to run the game I'd only make rolls on the Location and Effect table for some kind of critical hit.
