iGlide Quick Release Plate?

I am setting up an iGlide to work with a Canon S100 for shooting backcountry video. The iGlide doesn't come with a quick-release plate, so I am looking for a QR adapter to use. Weight is my first consideration–the smaller the adapter the better, and I can use a plastic QR to reduce weight. The adapter has to sit flat on the iGlide's mounting plate. I've looked on the web, but I'm not finding anything that fits the bill.

Any suggestions as to a QR kit that will work? Thanks for your help.
