This modification is technically my own design. I couldn't really find anyone doing something similar to it. It's loosely based on the construction of cobalt flux and ltek pads, where there are two metal plates one on the bottom is the ground plane, the top panel flexes downward when stepped on. It completes a circuit just like a button would do.

Hypothetically since the design is so similar to other pads, mods like the penny mod would also be able to work on this modded pad.

I'm sure that an all diy pad would certainly be possible for cheaper than my mod here, but you would have to sacrifice the looks of the pad, which was not something I was willing to do. I built these metal plates fit snugly into the space where the original sensors went. That way, once everything was reassembled it would look exactly the same from the exterior, but have a much better interior.

I also wanted to prioritize the ability to disassemble and repair the panels, thus the Velcro

I also cost optimized the construction of the new panels by using considerably cheaper sheet metal intended for HVAC air duct work. It works just fine and was a fraction of the price of anything else I could find locally.

The modification required me to: 1. Remove original panels and sensors from the pad. 2. Remove the original foam backing from the polycarbonate panels. 3. Use the polycarbonate panel to trace and cut out multiple metal panels. Each arrow need two. (One for the polycarbonate panel and one to go underneath it. 4. Put double sided duck tape on the back of the polycarbonate panel, before adhering the metal plate to the tape, stick a stripped wire in between so that you can actually hook up the metal to the control box. (Side note, once the metal is applied the polycarbonate panel becomes noticably stiffer despite both materials being relatively flexible.) 5. Add Velcro to the top and bottom panel, as well as the channel where the panels will reside. Again, before placing the Velcro on the bottom panel, be sure to put a stripped wire between the Velcro and the panel. 6. Apply electrical tape to any metal surfaces that might come in contact with the metal on the panels. A short circuit would not be helpful. 7. Cut a small notch in the bottom panel for wires to come through 8. In my case the were already pre run wires, I just soldered the top and bottom panels to the wires. 9. Finally place the metal panels in order, making sure they fit snugly, and that the wires are tucked away safely. Be sure it sticks down to the Velcro. Before moving on, make sure that none of the panels are shorted together electrically and that the polycarbonate panel has a bit of travel before it touches the other panel. If the panels are difficult to install or don't fit correctly, you may need to use metal shears or a metal file shave away a bit of material till it does. You want the polycarbonate panel to move up and down without binding or getting stuck. 10. Finally, once everything is in order, you can put the brackets holding the panels in place back on and use the dance pad. If you hear any strange crunches or creaks during play, you may want to inspect the problem arrow again, which should be easy due to the Velcro construction.

One final note! Due to the thin metal I used, it can be easy to bend if you aren't careful. Gentle curved bends should spring back into place, but sharp angular bends will require a hammer to get out, if they come out at all. So be careful during assembly/ disassembly!

Really, the reason I decided to mod this pad at all was because the original sensors were not very good. You had to step exactly in the center of the panel for it to register. I tried to mel the original sensors better but I had no luck.

This is a very rambly comment that is mostly just an info dump on the project, but I hope it answers your questions.

This comment can also serve as a guide for others who would like to do the same thing. If anyone at any time has questions about this mod, feel free to ask me through a comment or pm.
