Actually, I made more or less the same thing, but I used cable binder clamps. Using a long bit of cable lets me attach the Admiral's helmet as well as my own to the PCX, and leaves the underseat compartment for whatever (hi-vis vests at a minimum). Our helmets don't fit under anyway, so I am always using the Honda-supplied loop thing when I am alone.
I used three feet of cable, and it allows us to put one helmet on one side and the other on the other, nice and neat. I don't think I have a pic, but will try to take one when the season opens up again.
Here is a link to the clamps I am talking about, but they are available at your local hardware store for short money.

On my scoot, getting there is WAY more than half the fun!
