That's an interesting idea. I think this could work great in the Pi Zero format - compact, wifi + mass storage if needed and with the right wiring you could even flash the controller remotely via wifi. Could be a nice mix for projects where the size of another PCB would be problematic. The target audience would probably be smaller and I doubt the RPi Foundation would be interested considering their focus on education, but I would probably buy one.
