transition: ford to munition factory

what if we end the ford scene by "touring the plant" but its just a walk down the hallway. maybe starting with the father working on an assembly line then talking about the transition to a munitions factory with mother and father interacting in an assembly movement based piece, then involving the audience to get us back to under the balcony. id be sure to write it so that the mother could get behind the window in time for william to start. thoughts?
