In HIGE: land immediately.
In HOGE: how about pointing the cyclic towards a fixed point of the horizon, which means - with the cabin spinning - moving the cyclic in a counter rotating cyclic fashion, so that it points "away from tree/building/offshore-rig" towards the "desired direction".
W/o touchng the pitch the rotormast should inclinde towards "desired direction",
the a/c will pick up speed in that direction, and weather vane effect will stop rotation.
continue run on landing according to AFM.
Never done that of course, never heard of someone trying it either
,
but RC-helo pilots do a butt load of maneouvers with the cabin deliberately spinning,
hence they're rused to "rotating the cyclic". search for "prio",

Then again they don't sit inside a spinning cabin...
