This looks real simple. It might be easier than I first thought.
 Getting the roll pins out with Jean's bigger hammer goes a long way
 towards making this viable.

  I love your Rhino illustrations.

  Would there be an easy way to show how the sun-gear shaft/bearings fit
  into this. With some sort of vibration/damper/isolation between the
  rotor-shaft and the sun-gear I find myself puzzled as to how everything
  stays where it is supposed to be/

  The same way Tracy does it.

  The weak link so far has been the stock Mazda auto tranny flex plate.
  Ed Carver is working on fixing that as well.

 ...and the pin holding the sun gear to the input shaft.

 Yes and that too.

 Thanks for the pics. are you still considering the bellhousing,
or is it to mount on the front cross-member plate?

With minor modes it will fit either.

Here are some weight savings. The shaft and planet carrier combined is
4.8 pounds. The current Tracy shaft prop flange and ball bearing is 9.2 pounds perhaps a bit less as Tracy as drilled some holes in the flange.

The housing is 8.7 pounds which is about the same as the current Tracy version. Not including a large spacer Tracy uses between the housing
and the motor plate.

Input shaft and sun gear is 2.4 pounds.

The ring gear is 4 pounds but almost half of that can be cut off.

Planet gears, needles, shafts and spacers are .5 pound each for a total of 3 pounds.

Total is 21 pounds less the adapter plate and bolts.

The auto tranny bell housing is 8.9 pounds. Total about 30 pounds.
Jeff's motor plate motor mount is 6 pounds less spacers and long 8 mm bolts so that is pretty much a wash but the bell housing has no motor mounts. Motor mounts can weigh as much as 10 pounds over what is needed for Jeff's plate.

This box is going to save about 10 pounds over the current design.
That has a large effect on the CG as the box is almost the most further forward of all masses.
