As a note, this is possible through changing the core file rmmz_objects (or making a plugin to change the core file) in two places. Game_Action.prototype.itemHit and Game_Action.prototype.itemEva. itemHit is used for accuracy and you can define different hit types as different parameters (I have different accuracy for melee, ranged, and magic) and itemEva is used for dodge and you can have multiple based on the hit type.
