Lots of unanswered design questions here would come into play. Are you working with a cabinet dealer who will help you with the design? You can do very high stacked cabinets but will need ladder access. Otherwise you won't want to exceed about 50" for wall cabinets mounted 18" to 21" above your counter. If you do a European design of cabinetry, the cabinets can be short and sleek. The vent hood ducting can be angled through the wall to which it is mounted, so height isn't as much of a problem there.
