Interested in firing multiple speedlites into umbrellas or softboxes. Benefits would be more light and faster recycle times. I have a Yongnuo YN-622N-TX transmitter and 3 YN-622N receivers which are great for individual flashes in separate modifiers. Got a Flashpoint Triple Threat from Adorama ($12.99) just for experimentation. It's built like a rock, however, the 3 attachment point are cold shoes. I could attach the three Yongnuo receivers but this would make a kludgy, likely fragile monster. I note there are 4 shoe holders some with hot shoes, but you're still faced with triggering them and adjusting them for 1/4,1/8,1/16th,etc.

I've been concerned with that type of set up also. I put my Nikon speedlight on a PocketWizard Flex-TT5 transceiver and trigger it with a PocketWizard Mini-TT1 transmitter on my camera. It does seem fragile when mounting it by the hot shoe, especially with the Flex-TT5 underneath - it makes it even taller. It seems like a hit from the side could possibly damage the hot shoe.

I'm a machinist and made my own bracket out of Delrin. Delrin is a very strong plastic. I machined out a pocket where the bottom of the speedlight rests. The hot shoe with attached PocketWizard Flex-TT5 radio trigger is just hanging in mid air. There's absolutely no mechanical stress on the hot shoe. I've just been working on another bracket that will hold two speedlights side by side. You can probably make a similar bracket out of wood.

Hot shoe is exposed at the bottom. I attach a PocketWizard radio trigger there.

The sides are attached here that keep the speedlight from moving around

I have a manually triggered tri-flash holder that requires only one receiver. I don't use it often, but for that need, it has worked really well. You just need a cable to fit your receiver into a 3.5mm male plug.

This is similar to or maybe the one I have... it's packed in my auxiliary lighting case somewhere.
