Fastest way to purge is to run the car on a slight uphill or at the track at a higher RPM. Centrifugal forces would force the oil out faster then letting it sit.
Why not do both

Tweedboru, I love your solution. I would have kept it sealed with grease. In the end, all of the "lubrification in the bearing" is mostly used as corrosion protection and cooling. Splash will work fine. Bearings deteriorate when they pit so when people stop driving their car.
Maybe Porsche intended people to let their car sit a long time? All their anti-friction bearings are sealed one even those in the gear box where lubrication is plenty.
