It will work, since the only difference between them is the size of screen and shell, but size of buttons and other pieces should be of the same.
If anyone else comes on this, I can confirm the small 3ds buttons do not quite work right they are slightly smaller and the cut outs that keep the buttons from spinning around are not the same

Can someone provide further information about replacement of the entire C stick?
Or is it just as simple as pull the ribbon carefully, take the old one out and put the new one in?
There are two parts. The rubber bit, and the joystick assembly. The stick assembly is connected by 3 short screws, and inserted into the joystick board via zif connector. You need to unscrew the assembly to access the rubber bit.
