I have duly tinkered, and as usual there were details to sort out.
These two scripts can be used to move the top staff to the bottom and
back again:


8><8><8><8><8><8><8><8><8><8><8><8><8><8><8><8><8><
;;;MoveTopStaffToBottom
(d-IncreaseGuard)
(while (d-MoveToStaffUp))
(while (d-MoveToStaffDown)
        (d-SwapStaffs)
        (d-MoveToStaffDown))
(d-DecreaseGuard)
(d-SetSaved #f)

8><8><8><8><8><8><8><8><8><8><8><8><8><8><8><8><8><

;;;MoveBottomStaffToTop
(d-IncreaseGuard)
(while (d-MoveToStaffDown))
(d-SwapStaffs)
(while (> (d-GetStaff) 1)
        (d-SwapStaffs))
(d-DecreaseGuard)
(d-SetSaved #f)

8><8><8><8><8><8><8><8><8><8><8><8><8><8><8><8><8><

So these could be commands, or palette buttons.
If you wanted the Moves to be un-doable you would need to preface them
with (d-TakeSnapshot) as the (d-IncreaseGuard)/(d-DecreaseGuard) are
turning of individual undo for each step. Taking a snapshot first means
you can undo to your original state.
