Just been investigating if anyone had done anything like that, he apparantly just used PVC pipes, but had no takers in the trucking industry, maybe because it didn't really work that well.
I was also reading on some truck studies using slow flow between cabin and trailer, positive results in testing, but no real world test results.
My initial thoughts were if you could introduce some venting into the centre of the rear to disrupt or shift the vortex cycling and maybe help decrease drag, just investigating ideas.

See if you can scrape up an article on Ferrarri's 599XX racer.
They have 2-12VDC fans in the trunk which suck air from the diffuser area and blow it out where the tail lights would ordinarily be,at speeds up to around 150 mph.
They claim that if they pulse the discharge that they can intermittently detach the wake.They make no claims about its effect on speed or extended range on the track.
It's interesting reading.
It has been known for a 100-years that blown or suction slots near the rear separation point can lower drag remarkably.Georgia Tech is currently chasing this rabbit.
Historically,the energy to run the pump exceeds the energy saved,for a net loss.
Japan builds a 4-engined,jet turbo-prop STOL aircraft with suctioned wings and it has fabulous low speed flight characteristics.The downside is that the wings require a 5th jet turbine just to power the suction.Ouch!!!!!
