It's an intriguing hypothesis, but, to me, one look at the photo of the faceplate of that thing, with all the knobs and dials and lights and instructions, and my immediate thought was, No way in you know what would Amelia want to have anything to do with it. She was known to be very, ummm, "impatient" with any electronics beyond those absolutely necessary to make the aircraft go.
Witness her removing the Hooven Radio Compass (which may have ultimately saved her life if only she'd kept it), her reluctance to learn Morse Code, etc.
