Either one of these items can be moved to a different slot so long as it still is near the key body part (i.e. move the amulet of con to the belt or the bracers) for an aditional 50% to the price. also if you read the behind the curtain: creating magic items portion of the DMG it states that you can add an additional stat increase for a different stat by adding the price of the second stat increase + 50% to the cost of the original item (EX. necklace of con/wis = (wis bonus^2 x 1000) + (con bonus^2 x 1000 x 1.5) )
