ok, well i just got smart and figured this out for myself. the answer is yes!
here's what i did...
1) make a simple program to run on the wii which says which buttons are being pressed
2) connect my soon-to-be-improved wiimote to the wii and then remove the upper cover
3) start my program
4) using a length of wire, start "pressing" buttons and connecting the exposed traces from different buttons
the -, home, and + buttons have 4 corners exposed. the 2 left corners share the same current and the 2 right corners share the same current. so i can use those to solder to without needing to remove the existing metal caps.
button | trace
u | left = ground
d | right = ground
l | bottom = ground
r | top = ground
1 | left = ground
2 | left = ground
- | right = ground
+ | left = ground
A | right = ground
so, by connecting the left trace from the up button and the left trace of the down button, the wiimote thinks that i have pressed down.
