GoPro to YS Adaptor / Clamp?

I've got a INON Focus Light which is mounted to my tray via a YS Mount (like the Nauticam cold shoe one)

When I'm doing WA video, I was thinking of mounting a GoPro to the same mounting point, however I can't seem to find a GoPro mount to a YS Mount - does such a thing exist?

I have the GoPro attached to the cold shoe on my NA-GH4 via a loc-line adapter on the cold shoe side, and a tripod mount with loc-line on the GoPro side.
