Not a pro, but I think that would be a killer 4/3 setup. The term 'downgrade' is a bit subjective, imo. People don't buy into 4/3 because they make the highest quality images and to heck with everything else. It's a trade off for the size. If you have no issues with the size of your D7000, then I think it would be an unwise move, imo.
