So, the basic Idea of the build would be to get each component of the project working separately.

I have a couple of pinocc.io dev boards and to get them to work in a P2P configuration would be trivial. 

I have run the lcd display and the mp3 decoder + 8 Ohm speaker using pre-existing arduino libraries.

The only part that I need to work on is the 20 x 20 touch pad. I want to check if the touch pad can be driven using the pinoccio itself. That way we can avoid the STM32F4 altogether.
