Is there any product that you can buy that can be overlaid on the MacBook Pro's Touch Bar to simulate physical keys and hide the actual Touch Bar?
i.e, you'd configure the keyboard settings to use traditional non-changing function keys, and then you'd stick some sort of physical button strip on top, and it would function like a traditional Mac Book Pro.

One solution (albeit, a bit of a hack) that I found is to place a wireless magic keyboard over the top of the built-in laptop keyboard.
If you place it in the right spot, it doesn't press the underlying keys (although see Karabiner information below to stop this issue).
As someone who despises the low action of the butterfly keys, this has the double benefit: (1) it restores traditional escape and function keys, and (2) it provides the awesome keyboard experience of the magic keyboard. It also means that you can use the trackpad.
It can also help to use Karabiner to disable the built-in keyboard when external keyboards are plugged in. This overcomes the problem of accidentally activating the keyboard undeath when pressing firmly on the magic keyboard.
