I haven't heard of anything for that, but it's
possible that the kernel input layer can be
configured like that.

At least "jscal" utility manual page states that:

"jscal  calibrates  joysticks  and maps joystick
axes and buttons.  Calibrating a joystick ensures
the positions on the various axes are correctly
interpreted.  Mapping axes and buttons allows
the  meanings of the joystick's axes and buttons
to be redefined."
