I could throw in my hat for number 8, but add the following.
Like a Dove Board - more RAM for a Mac 128/512.
Since it was never implemented for the Classic Mac, add a FPU to the classic 68K. I believe this was in some Amiga. From what I read in my 68K Books, you can add a FPU to the 68K. It would definitely speed up some things for the Mac classic series.
I would also love something like a Commodore PET's IEE488 parallel output for the Mac; where one can interface hardware to the Mac directly. It would be more like a GPIO on the Raspberry Pi, but on a Mac it would be great.
