What arrangement do people have with their sidedraft A-series Datsuns?

I have my catch can right up the front near the radiator which collects from the rocker and crankcase breather. Normally at idle the radiator fan blows most the extra smoke rising from the catch can filter around and under, but after a a fairly spirited drive when I pull up at the lights there a fairly noticeable (but small) plume of smoke coming from under the bonnet.

I really want to route the line back into the intake but not sure how to do it. I have socks no air box and was thinking of somehow putting some nozzles on the underside of each of the velocity stacks to take a small line carrying the fumes, from the catch can.

Does this make sense? Anyone have a smart little setup? Not too keen on tapping into the manifold but I do want to see some pics if you have done so.
