How about tipping the carboy a few days prior to racking then keping the cane above the lees until you get closer to the bottom. Get as much as you can until you start sucking up too much sediment. Then pour the rest in a smaller container and let it sit in the fridge until those lees settle. You shouldn't lose too much. If you add bentonite to the leftover it will thicken the lees and clear faster. Just my thoughts.
