it is definitely possible, the issue here is that we have currently no
install process beyond "dd this image to an SD card", which is why all
images are focused on that ... 
there are plans for a "recovery mode with install option" that should
allow you to install from a booted SD card to some internal flash device
but i do not know if this is a 16.04 goal (if it is, it is quite late
for it though).

also we currently use a plain ext4 partition for the writable bits, this
probably needs to be turned into a loop mounted image or we need to add
support for additional filesystems to the boot scripts when sitting on
one of the above filesystems...
