They used to make cardboard guides that could sit on top of the older ibm keyboards when most of the world used one... I don’t know that you can replace the feel but some haptic taps or something might improve the touch bar. I generally like it bur on it and my older MBPs I pretty much used escape and volume and screen brightness settings and otherwise never used that row. Since laptops, the f-keys simply aren’t what they used to be, it’s not unusual for them to be overloaded or even require a shift like key to be pressed for f-key behavior.
