Hi, yes it should be possible, check here. It should be also possible to make FM working.
BTW: nicely done! I am also thinking about something like that, the Brainiac is too expensive and this looks is much cleaner, I have 3D carbon wrap that I would like to use instead of paint. I was also thinking about 12" tablet, it seems you still have some room, so I guess it would fit, what do you think?
