No, if you (as a contractor or employee) make more than $600 from the same person/business, you'd be obligated to report it, which would in turn make them obligated to report it, even if they didn't realize you had done more than a single contract for them. For this to work, you'd have to have independent shell corps make each chunk of work as well, which .. is probably also illegal. What could work is a middle man (ala upwork), but then you'd have to accept the middle man knowing you.
