What about something like this on the rubber elbow?

Is there anything wrong with connecting the air return pre air filter? Even when hot and driven at 22psi there is no noticeable residue in the outlet. It is just a matter of space

Personally I wouldn't put it pre-airfilter. You might not see anything noticeable now, but it could be a different story once the vehicle is heavily loaded for a trip, or towing. I think it would only take a small bit of oil to clog a paper filter pretty badly.

How about extending the outlet on the filter housing so that comes around the bend as steel rather than the rubber elbow. You could then easily weld a fitting onto it.
