The other way around, fire tv on generic android box?

Sorry if this is dumb/answered ? but their is so much noise about jailbreak/rooting fire tv hardware I can't seem to find if their is a way to load a fire tv rom onto a generic box? I'd like to take a generic quad core ish box and spoof it into a easy to use 0 fire tv box, I planning on giving this away to my aunt and for ok, but at 0 not so much.. I thinking I'm gonna end up with getting the ftv stick, unless their are free range fire roms I'm unaware of??

The IR Reciever with a Generic Remote

I have an old Harmony One remote, but there are reasons I don't use it. It's clunky, needs charging and I just don't get on with its approach of reverse engineering all my devices to work together in "harmony". The price tag is also a bit much for what it is (I didn't pay for mine). Some people do get on with them very well, I just don't.

So does anyone know of a way to program the Shield to respond to the IR signals of any old remote? I mean something similar to LIRC, but I don't want to buy a FLIRC.

What would it take? An app with root permission? A custom ROM? A port of Ubuntu with LIRC? Is it even possible?

PS: I don't mean to hate on the Harmony users.
