Paul,
I had a look at your drawings again and I agree with you on the simplicity of your design, I like
it !!
I also looked at the Ross set-up and it is very simple too, although a bit rough it quite
obviously does the job.
However with the 6 pin planetary there is insufficient room to just put some bolts through (4pin
yes, there is room). It would require me to remanufacture the planetary housing, although not
impossible, it does add complexity - something I was hoping to avoid !

Ah ha! I am way ahead of you. Just replace all six  pinion shafts
with hardened and ground custom made shoulder bolts. Leave
the carrier as is. Hardened and ground spacers would
work as well. Counter bore the bulkhead so the spacer
or shoulder bolt just fits inside the counter bore to take 
the sheer load. Sort of like a dowel pin.

Someone was converting the 4 pins to six pins, using aluminium for the planetary housing - is
there any information on how this was manufactured ?

With an NC mill. Here is a pic. We don't need to do this anymore.
I think Ford read the news letter and decided to do it themselves :-)

Although I don't intend to use aluminium, I thought steel 2 plates with 6 spacers with through
bolts would be sufficientI just don't know if bolt/spacers would be rigid enough.
considering the torque going through it. (what do you think !?)
My thoughts were that these bolt/spacers could be extended to go through a plate attached to the
shaft (somehow).
I do appreciate the effort - this is great info you are giving me
