Also, Callisto's orbital radius is a bit larger than the diameter of the sun, so it would only co-intersect about half the time (less for non-orthogonal transits)...

I would imagine Kepler can find Mars-sized moons for sure, as it can find Mars-sized planets. I wonder if, after a planet has been found, and special attention is goven to its light curve, if smaller moons could be found. Perhaps Titan or Ganymede sized moons. I doubt we'll know much more about it than it's radius, but still. Would be very interesting. Wonder if a transiting Titan were to be found, if its atmosphere could be seen.
