Rob,
Few thoughts.
First I think your idea of a tap at the top of the siphone or u-tube into the venturi side of a power head is a decent idea. I have been meaning to try it on one of mine that has a low flow rate to help with bubbles. As others have said though if you have enough flow rate through the tube it will not be an issue.
Another thing I did on mine which helps with bubbles as well is added a little baffle on the intake box around the u-tube. I was finding the flow into the siphon box was so much that it was causing water turbulance and creating bubbles that would go into the u-tube. With that added baffle its not a problem.
Lastly, on your question I would say don't glue it. I tried that the first time I made an over-flow and well it was bad lol. What I have done on the two I made sense then was drilled a hole and used nylon nuts and bolts and then covered / sealed them with aquarium silicon.
