I tied mine out of a continuous piece of rope, so the standing end comes from the outside wraps. That's much more secure than pulling on the core of the knot itself.

It's legal. But you'll have to make sure the connection between the different ropes is strong. The bigger the difference in diameter, the more likely you'll run into issues with the bend. There are several knots that are well suited for tying together two ropes of dissimilar diameter though.

Thanks so much for posting this picture. I had not seen the clevis pin before now. I wonder if someone could ask in the Q&A if teams are allowed to attach to the pin itself with a loop, and not rely on a stopper knot. That'd be far more secure for smaller diameters of ropes and straps of webbing.
