I am still not understanding why you need vertical adjustment in the first place. Why not just shim it and lock it down?

I am not very confident in the way it will sit level with the cast iron table of the saw on long term
I suspect that the screws I use to attach this to the rails will have some play and they might allow the brackets to move downard after all is let say shimmed as you indicated. Then I will have to shim it again
Besides that the table will be a consumable -cheap melamine easier to replace this way. I might just do what you said as well, I will see how it all comes together
