Carl: If it managed to get the cumulative mass of Jupiter, Mars, a few moons, and some asteroids, not to mention the different orbit, would cause some effects due to gravitational pull, with (I'm guessing) could cause some slight changes in the orbits of the surviving planets.
Mongoose: My post was more along the lines of what the effect of a black hole with less mass than the moon, due to the expulsion of matter/energy in the form of Hawking radiation, would have as it would throw off the already slightly unstable spatial relation between Earth and Luna.
