Hi Paul...

I might be interested in doing some reverse engineering on the castings.
Another way you could increase cooling would be to have fins on the inside
water jacket area. This would increase the surface area for heat dissipation.
 Solid state devices use this tech...as long as we are working on high
density power to weight ratio.

I think the fins on the inside are a very good idea.
As I mentioned, building a thermodynamics test rig to test this is 
not all that hard. 

BTW Instead of feeding cool water into the front of
the block I think it should be fed into the center housing and allowed
to divide front and back. Mazda did this with the four rotor.
As it is now the rear rotor tends to run hotter than the front rotor.
