Chan, There are multiple difficulties.1. The smoke controller is multi-layer. The smoke unit is special, high temperature material. I do not think a multi-layer board would work well. I'll check with the board manufacturer.2. The smoke unit gets very hot. The electronics, especially the microprocessor may not function at these temperatures. We would have to measure and guess as to the highest temperature.3. I would need about 5/8" extension of the board. Would this work?4. The board thickness needs to be the thickness of the existing smoke unit board. Another possibility would be a connector change on the smoke controller. The thin connectors only, one on each end. The thickness would decrease significantly. The smoke unit could alsouse the thin connector, allowing thinner, more flexible wires. Sincerely, Marty Pierson
