Don't know why anyone would want the extension 1" back on top of the pullback already in the riser either. If you think about it, the + 3" extensions will bring the bars back closer because they follow the angle of the riser, they do not go straight up.
Look at the bottom of the stock riser, you will notice two small holes for the rubber bumpers. When you mill the extensions make sure to include the holes on bottom. The bumpers can be removed from the risers and installed on to the extensions, they need to be there to prevent vibration. Also, if you put the holes on top of the extensions as well they can be used for dowel pins. By pinning the extensions to the risers it will give more rigidity as opposed to being held together by only the riser bolts. It would also help align the spacers to the risers and keep them aligned.
I share this info because it is exactly how the pair I purchased are made.
Hope this works out for you guys, I had a hard time stomaching the price when I purchased these...good thing Bitcoin is up LMAO

They have 1.25" of lift, very mild. Its just what I could fit in some scrap material I had laying around. I think this minor adjustment will be well and fine for my use as I barely wanted to change it anyway, I will see how it feels. In the meanwhile, I ordered material to make them in some longer sizes to try out also. The tooling that I had to make for producing these 1.25" blocks will accommodate up to probably 3" blocks if I wanted to go that far.

Man those are some big clunky chunks of metal. They look like miniature bridge abutments and I'm not sure I'd be comfortable with one bolt going up the middle to hold that sandwich together. But what the hell. Motorcycles are supposed to be dangerous, right?
Now these are some beautifully elegant risers.

There is certainly nothing wrong with being cautious and curious when it comes to ones safety. But you are not going to make those riser extensions fail. The assembly is most likely far more rigid than what you have posted as alternative, unless those are a hardened steel. The footprint on the aluminum extension is at least 3 times larger, and the bolt passing through the middle is large enough that you can likely hang the entire bike in the air from just 1 of them.
