"Inherit bends of parent" won't help with what you are trying to do, but if you want to know how to do it: From the menu bar, Object > Change Parent, there is a tick box "Inherit bends of parent". If you decide to try making a positioning morph, the easiest way is probably to use a magnet on the prop. Scale the MagZone way up, apply the face morph to the character with a value of 1.000, use the magnet to translate/rotate the prop into the correct position. Spawn a morph target, resave the prop to a pallet (with a diffrent name so as not to overwrite the original).
