It would still require someone to weld the seams, but tube-in-a-hole is easier than plates-hanging-in-space.

The solution to that is simple.
A 6 inch diameter circular aluminium plate with a rounded square hole cut in the middle of it. I know a really competent welder who can weld anything. The secret to any project is finding good honest people who you can trust.
