At MSR-Houston, our cage was not checked for wall thickness. However, under NASA rules, cages are required to have small inspection holes drilled out so that tech inspectors can check the wall thickness. I suspect that if your cage gave the appearance of being substandard, they'd require you to drill a hole and prove that you're using tube that is up-to-spec.
You're likely to spend a lot more time and effort building the cage than nearly anything else for a Lemons ride. I sure wouldn't want to jeopardize that by using non-spec materials just to save a hundred bucks. It wouldn't pay off economically at all if you were to get to the track and then get bounced for the non-spec cage.
And that's not even discussing the safety aspect.
