I remember people making hacks of their GBA, upgrading to a better screen that still worked wonders, with a better image quality. I though that touchscreens could be swaped as easily as that lol.

A GBA screen is not an input device.  It doesn't matter what type of screen you use for something like that.  A GBA screen only displays the signal sent to it, it does not return a signal back to the system.   It's like using a differnt TV with your game console.  Same signal.

A touch screen is very different in that it must send electronic signals from the screen back to the system in a manner the system is designed to understand.   Resistive and capacitive screens have different signals.

They're still digital. It wouldn't be an issue to convert the bits into a form the Wii U will take. Wouldn't take a special chip, just some routing on the controller logic. You wouldn't get increased resolution but changing sensitivity is possible.
