I had a similar problem back then, see how I fixed it here:

The most sane way is probably to only install 4 OSes, which is usually
enough for a smartphone. For everything else you need a custom solution,
which might get difficult.

All I know is this project:

It wasn't officially announced, yet and doesn't seem to be very active.
