I'd tee all the lines together and use a single vapor/oil seperator can (Moroso sells a good one) and vent it downward with a mesh filter on the end. The seperator catch can collects the liquids, and the vapors pollute the air. Starions used a similar system on the pcv outlet hose to keep oil droplets off the turbo, with a drain line for the liquids back to the crankcase, the latter not an option for you. The Moroso can removes with a quarter turn and you dispose of the goo in your dump of choice.
