I've thought about this type of multitasking before when I see, say, an icecream parlor or a coffee shop in a strip mall. The icecream parlor makes most of its money in the summer, the coffee shop makes most of its money 6am-1pm (I'm guessing). Why not have an AM coffee shop and PM fast-food joint? A summer ice-cream shop and a winter hot-chocolate/cookie/pastry store? All you would need cables and rigging to hoist the unused equipment up near the ceiling. Maybe a 15min turnover and your business is making money for another 8 hours instead of sitting there vacant. With counterweights, locks, and mechanical advantage, you wouldn't need any motors or control systems. I think even a gas line could safely be made to move up/down 6 feet each day. This would all be done by a specialty outfit, not ad-hoc by restaurant owners. All certified and up-to-code.
