Yes, this is a good idea. However, if you decrease the signal-to-noise ratio, someone may still be able to extract the signal. So then the challenge becomes to make the noise look like a real signal, which may be quite a challenge.
For example, Google can figure out if you are a bot with its "I'm not a robot" checkbox. This means that they can probably also figure out that fake automated requests are indeed fake.

Not necessarily. Given a noise script doesn't have to run unattended, the script could easily just prompt the user to solve any captchas it encounters, so that couldn't be used to distinguish real from fake.
Websites could have hidden captchas. For example, a website could track the movement of your mouse pointer and compute whether the movements most likely correspond to a human or not.
