Is it legal to make a custom slip ring?

Seems like it would be legal with 12 AWG elsewhere. The downside is there would be no contacts available for any kind of speed measurement for a motor on pivot swerve.

I spent sometime looking at these, and decided a coaxial swerve was a simpler approach from my viewpoint.

The question is... Are two connectors each rated for 30A, placed in parallel, gauged correctly for a 40A branch circuit? I could make an argument in either direction. It really would need a GDC ruling on it through the Q&A.
