Paul,

Would it be reasonable to route a tube from the vent port at the neck of the
oil fill to the intake manifold since the engine needs oil anyway, or is
that a bad idea?

That might be OK for awhile. On the other hand it could gum up the apex seal slots which is  obviously  not a good thing. Crankcase oil is not the best for apex seal lube. Two cycle oil burns much cleaner without residue. I would use an air oil separator and route the output back into the oil pan. Overboard makes a mess on the bottom of your fuselage and could reduce the engine oil supply on long flights.
