Limit yourself to 16 processors and cram the whole works into two nybbles. Sort of the opposite direction as the 65536 cpu version.
Not sure what the advantages of the 8-bit or 16-bit version are over putting everything in a 32-bit value. Most of my systems like to talk to RAM in 32-bit chunks (or larger). And all of my linux systems have 32-bit registers (or larger).
