I want to learn pcb design in Eagle/Fritzing. So i was thinking of using existing amazing Arduino mini/nano in eagle and create a custom pcb which has all arduino capability and plus some components like 7 segment/Bluetooth radio etc.

Can we do that? Is is allowed or arduino design is not open to be modified?
