 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.

Routing the cooling is an excellent idea, this give the same water temp to
both housings.

Another Idea, Split the casting into two parts for manufacturing.  Take
advantage of technology and assemble after final machining.
