Gauging interest in rear box for Cube Aerium C68

I’ve got a potential customer asking me to design a rear box for his Cube Aerium C68 size small. Wondering if there are any others with the same bike in small or other sizes that are looking for a rear storage box for their bike.

If there is anyone in the San Francisco Bay Area that would be willing to let me measure their bike that would be a bonus.

Here’s a sampling of the boxes I’ve designed for other bikes
