Either way, I will make some up and let you know how they work out.
We bought pulley stock and machined it down at home. Not too hard to work with. You'll want a number of teeth divisible by three if you can in order to make it easier to hold in a three jaw chuck, but it machines easily and you can easily remove the hub or any other features you might not want.

This year, since we do belts-in-a-tube, we just had a single piece of pulley stock both belts ran on. Worked great.
