I'm working on a partially similar solution as well :) hopefully it will be ready to release in the next weeks.
In my setup I did not change the top board but reprogrammed the PIC MCU instead to be able to interface properly with my replaced controller board at the bottom.

What did you use on your top board at the touch sensing section? I'm interested in the plastic stuff.
