>How the hell are you going to draw in the vape air from your vaporizer through your bong?

think of the end of the vape hose or the volcano 'mouthpiece'. For the Vapor Brothers whip end I took off the rounded mouth piece and replaced it with a 2 stage glass piece. One end fits tight in the whip hose, then there is a rubber washer piece to make a nice fit for the other glass end piece that fits into a glass piece coming out of my honey bear bong. So I put the end of the whip into the honey bear and inhale out the top. Same thing with the Volcano mouthpiece...I just put the end of the mouthpiece onto the honey bear piece, use a little pressure to open the valve of the Volcano piece and inhale. It works perfectly! So I imagine you could put oil into the honey bear setup, or have a second one to exhale into. I bought the parts off-the-shelf from my local shop.
