Welcome that is a very noble plan for the often unappreciated caprice wagon (I call those cars rolling caves because of all the space they have). Being a shop teacher you have more tools and tech skills than most of us here. You should develop a kam back, air dam and maybe side skirts out of some aluminum sheet metal. The kam would help with your over-the-limit speeds and the dam might as well. Looking foreword to seeing pictures and/or progress on the "cave", you are doing great already!
