Sure you can, but it's not trivial to make the random seem like a human random at a large scale. What are the parameters of a human slide and what kind of distributions are they? And there might be things they do under the hood that affect those parameters like fingerprinting. You would need a lot of data to imitate a human, but the provider of the captcha has a lot more data than you to counter your effort.
Thats why it's usually just easier to pay some people pennies to solve them by hand.
