From 13 inch to 14 inch

I know 13 inch 3:2 is pretty close to 14 inch 16:10, but there are just much more options for screens for the latter, like this with 100%DCI-P3, 120hz refresh rate and VRR, but current top cover could not fit. So I wonder if its possible to make a new top cover, input cover kit, and bottom cover to make the laptop 14-inch.

Sure, just design the 3d files and get someone with a CNC to mill it for you.
