I agree that it's probably possible, but IMO you're going to
spend a lot of time trying to make everything fit -- effort
that could be better spent on developing and testing your
application. I'd recommend a serious look at using something
intended for a smaller footprint (XMK, FreeRTOS, uC/OS-II, etc.).
