Looks insane as always.
Just some food for thought though, are you sure the aluminium intermediate "iron" you've drawn in cad there is strong enough?
Remember, rotor housings want to do this, especially in high hp high boost applications:
The rotor housings need the strenght of the intermediate and frond and rear plates, or else they would seriously warp.
This is also what causes the rear iron to break on older rear iron's.
Your design doesn't look very strong in this area. The steel inserts don't add strength, and the aluminium part has a lot of cutouts, so that's not very strong either.
Ever thought about making the steel insert a bit larger?, like just a little bit smaller than the outer o-ring groove?
That way you can drill the holes for the engine bolts and dowels in the steel insert, so the steel inserts add strength to the engine.
