I think it should be.  As I understand it, the joystick ports on the C64 are
wired to the bidrectional parallel pins on the CIA, so it seems like it
would just be a matter of setting the data direction registers as

Not much, unfortunately.  The base system comes with only the temperature
probe, which handles a 23F - 113F (-5C to 45C) range and is basically a
thermistor on a wire.  Its response is not particularly linear -- after
calibration it's accurate to about 1C at the low end and 2C at the high end.

I know there's a light module as well, which I assume is just a
photoresistor on a wire, but I don't know if any others were produced.  All
of these was released in 1983, which was a Bad Year for Atari...
