You could use the Wii motion controller to insert a new GPU and CPU into the console via a Mario game... (Just Kidding)...
It doesn't seem to be technically possible, and there in lies the Nintendo NextGen million dollar question which may or may not affect the longevity of the console going forward. 360 and PS3 could add better motion controllers... All three consoles are stuck with their current graphical, processing, and sound features.
