Would it be possible to replace the touch bar with normal fn keys?

"As you can see, entirely different machines.

I don't believe this will be possible, Apple has to squeeze everything into such tiny space, therefore practically left zero space for any modifications and parts have to be custom made for each model."

there is probably a board under there, which is probably heavily screwed or glued on, the oled panel itself is also glued on, macOS would probably give you an error since it wouldn't be able to detect the touch id sensor so you would probably have to reroute many cables, which might not even be possible

I wonder if you even need to alter the chassis. The MacBook Air keyboard might simply fit, and the connector for the real keyboard portion of the MBP may be the same.

"In keyboard options there’s a checkbox to permanently make the function keys stay on the touchbar.

all it does is swap over the fn functionality so that instead of showing you the fun keys it shows you the touchbar instead.

theres no way to physically swap out the touchbar though, just the software option to get them back permanently or app specific. I customised mine so I’m happy with it, i hardily used the function keys anyway for most apps so it’s a welcome change that needs some more software tweaks I think."

The dumb emoji bar sucks even if you have it set to show function keys all the time. It still "sleeps," so you have to hit it twice to reveal the Escape key (for example). Also, Apple's baffling ignorance of the Delete key continues... you can't even add a legit Delete key to the emoji bar, even though it's a strip of soft keys! WTF!
