What I would try if I were in your shoes could be to see if I could emulate the Kobo on a PC. It is a Linux based system and there might be chances to make it work with virtualbox or wmaware. Maybe, it is not a good idea (I am not an expert of virtualization) but if you would be able to do it then you could make all the test you want without harming your real device.
