I don't think this will happen in order to scratch this pretty unusual itch.

One way you can solve it for yourself is by rewriting (with dd) the
first sector that contains the partition table and rebooting.  So you
can have two "views" on to the rest of the storage exposing just the
partitions you want in each view.  That'd get you 14 partitions and the
ability to share eg /home between the two views and so all OSes.
