Works that way in Black Hack iirc & in the Talisman RPGI was also tinkering (i.e. using currently) in two games the idea of a shield being able to be "sundered", whereby it is destroyed, but ignores the damage done on that hit. So a shield bearer could use it for a big hit, or when they're down to a couple Hp, etc. The +2 would probably work since the shield provides a pretty big benefit (albeit one time, unless you bring multiple shields - but watch that weight!).
