Is it possible to rig an AOI quick-release lens holder to an AOI cold shoe mount, possibly something like this or this? I plan on taking out the M52/67 threaded mount and rigging the quick-release lens holder to the cold shoe in its place. Originally, I bought two QRS holders to mount onto my arm sections to store my wet lens and macro diopter for when I'm not using them. However, I realized this would cause an uneven weight distribution which might make maneuvering the arms a bit more difficult, and I would not be able to fit enough floats on the arms to make my setup neutrally buoyant. I also figured I would need only one lens holder as I would probably be using either one wet lens or the other at a time, but not neither of them. Alternatively, I could mount the lens holder on another arm section attached horizontally across the handles of my tray, using triple clamps to attach both the horizontal arm section and both my arms. However, this solution is more expensive, so I am trying to make cold shoe solution work, if possible. I believe the QRS lens holder probably will be able to be bolted onto the cold shoe in place of the threaded mount, the problem then would be will the QRS holder be fixed in place on the shoe or will it spin. In the QRS holder for Ultralight arms, the lens holder is held in place by two prongs where the lens holder screws into the arm mount. I noticed on the threaded cold shoe lens holders that there are two holes that look like they might be used to interface with similar prongs. If anybody has both of these mounts on hand, could you test this for me please? PS: If you have the single QRS mount (as opposed to the twin mount), I believe you have to take the square nut out of the lens holder, which you might not want to do.

I am an amateur underwater from the PNW, although I really only dive in tropical reef places during vacations. I got into this hobby through iNaturalist and wanting to document what I see while diving, and I got into scuba diving itself from the saltwater aquarium hobby. The main places I have dived are in Hawaii and the Caribbean, though I have also dove in Fiji, and Indonesia (specifically Komodo). My current setup is an OM TG-7 with a Backscatter/AOI UWL-M52 wet lens and two Backscatter Hybrid Flashes, though I am in the process of upgrading to an Olympus EM10 Mk4. My main subject of interest is stony corals (especially larger-polyped and fleshier ones), which is what I like to photograph underwater.
