I was wondering if there was some kind lightweight "shoe expander", although I have no idea how it would be called if it exists, basically a metal structure that would sit on the shoe that is located above the built in mic and extend to two arms, each of which will have shoes as well, so if for example you want to use an on camera light and a second microphone, you can use both, as long as they're not too heavy together. I've been looking for this on B&H but I couldn't find anything.

My goal for this would be to use my light on one shoe and then the Zoom H1 recorder on the other shoe, or perhaps a stereo XLR microphone, besides the mono directional microphone I use on the clamp.

Does this exist, and if so, what is it called?
