Mark,
I just re-visited this idea and it was really growing on me.  Then I decided to order a fly wheel!  :-)  But I think it could work well.  IMHO, welding would be better to stiffen up the 13B plate to make up for the loss of its attachemt to a ring gear.

All,

Attached is a picture of my proposed solution to the cracking flexplates.  I used my old 13B flexplate, removed the ring gear, and nested it inside the 20B/RX-8 flexplate.  It could be held together by bolting or by welding around the outer perimeter, similar to how the ring gear is attached, although welding may cause warping.  If bolted, there would be ten bolts holding the two flexplates together.  I favor the bolting method as the four bolts holding the aluminum adapter will be a bit tricky to install and bolting would make it a bit easier to assemble.
