If i was building something this big, id probably scale everything up. Id scale the corners etc for sure and go with bigger conduit so you can support the longer run.
Of course that issues in new problems of the middle z.
scaling the outside pieces is easy. just scale correctly and build it. (and bigger bearings)
the middle z is a work of art and would not be super fun to scale, although theortically still possible
