Could SFOS run in container on Android device?

Would it be possible to have SailfishOS running in an Android device under the original OS, for example in a container?
I know SFOS can run in virtualbox but that is strictly X86 implementation so something else should be used for running the system on ARM platfom. The solution could be a lxc or qemu -based implementation.

In essence what I’d like to see is the reverse of Alien Dalvik, being able to run complete or partial Sailfish implementation on a Sony Xperia 10II device along with Android as the host environment.

Has anybody ever tried this or thought of something that might block or enable the idea?
