That may not work. The pin is riveted to the large chainring, so there's nothing sticking out of the back to cause problems with the middle ring. Attaching a screw would likely leave the screw head in a position to foul the chain when I'm on the 36. I might look a this, though. I was quite surprised at just how large the gap was...but I suspect you're right, this crank was designed in the 7-speed days, and 9-speed chain is a good bit narrower.
