I got an email back this afternoon:
"Tom,
I checked with our stand guys. I was told that the width of the cup would not accommodate 2 of those devices. "
The Reo Grand is only 1.5mm wider and 1mm thicker. I bet it would work.
Interesting. It doesn't seem like the dimensions are that much wider to me, but then I'm not the one making them so what do I know lol.
