Just a nit, but "over engineering" would be if you optimized the heck
out of it. This is "under engineering" or just brute strength
designing (if you can even call it that).
Over engineered would be a aluminum tube space frame, stressed member,
composite deck, etc.... to carry your lawnmower.
Never understood why something that was nearly the opposite of
engineered was "over engineered".

Properly welded you don't need the bolt. Get it welded RIGHT and forget
the bolts and associated gadgets. If you don't trust some weld, i.e.
the strength of a corner, use bracing across the corners - also welded.
Don't forget the plate on the top is going to be some reinforcing for
the whole frame.
