Stan I'd pick up a used fairing off CL.. you'd be hard pressed to DIY for under $50 when you factor in the mounting hardware. Even if you get a smaller one today, if you decide you want a bigger one later you could recycle all the mounts, and just swap out the plastic part with a larger piece of plastic. But the small one may be enough to knock down the wind noise anyway.
And to make all the Yakima stuff work, try a 1" section of sprinkler tubing, split lengthwise. Then snap the tubing over the bar, which quickly turns the 1" bar into a 1.125" bar.
