It is doable though. A bunch of years ago I followed some instructions and set up a dual-boot on one using a Chinese ebook platform firmware. This way if you wanted to read epubs or PDFs you would boot to the other OS. Worked pretty well! Had access to all of the hardware including wifi. So it would be the same basic principle here as what you envision.. boot into that other system, but have it instead launch some other app.
