Yes, many piezo technologies are similar enough that they will interface successfully. Often the biggest difficulty is getting parts from different manufacturers physically hooked up together. Other companies don't use the nifty plug-in connectors like the ghost system so there will be more work.
An inexpensive way to interface another manufacturer's piezo bridge with the ghost system is to order the Extension Harness and solder wires from the bridge to the pins on the harness. That way the other manufacture's bridge will plug in to the ghost system.
