I dont see them being able to rotate it reliably. But in a standard 8 hour shift they could swing it a little. Now everyone in that 8 hour shift time block will have to share the downtime but they could take it down for 4 hours at the start for say 4 weeks and then the end for 4 weeks. That is probably the best to hope for. They may also need to move the days by 1 as well but that is the solution I would strive for.
