As said in an earlier posting, the part 9995-9 is now in DIS, which

Thus, there is enough time for any manufacturer of operating systems
or third-party software suppliers to announce their support of any
keyboard layout compliant with a standard referring to ISO/IEC 9995-9.
Again, just speaking about one platform (Windows) that seems to be in
somewhat common use, the problem is that the underlying architecture
doesn't support multiple dead keys on a single base character, nor
does it support a fifth, sixth, etc. shift state (unless one chooses
to be reckless and use Ctrl). This is unlikely to change in the next
two to three years. It isn't a matter of providing a layout—otherwise,
anyone with MSKLC and a supported Windows version could create one.
The only limit I know for Windows’ dead keys is that they can’t handle
characters outside from the BMP.
With MSKLC, it is possible to support multiple dead keys on a single
base character:

(I didn’t say it’s easy: you need to edit the klc file with a text
editor and to compile it manually.)
Using the same technique, you can even make a compose key.
And for the 5th and 6th layers, perhaps you could look at the Neo layout
(a Dvorak-like keyboard layout for German, http://neo-layout.org). They
made Windows drivers for their very special layout which uses three
pairs of modifiers: Shift, Mod3 and Mod4. You could certainly find ideas
there.
