I suspect you're on your own a bit here. The Cressi and Supra PCDs are the same.
For the fronts, your problem will be the rotor height. The relative heights of the rotors is quite different. 323 mm Supra rotor is 18mm lower than the Cressi height - this might result in the caliper clashing with the back of the wheel. You'll need to scout around with some Verniers and measure things up. Whatever you end up doing you'll definitely need a caliper bracket made up. I suggest you look outside Toyota for some more adequate rotors (DBA catalogue).
For the rears, your limiting factor will be the internal drum handbrake diameter, which I think will be 190mm on your Cressi. MA70, JZA80, xZ20 onwards Soarers all have 190mm internal drum handbrakes, so they will have suitable rotors for you. The next problem will be rotor height and they all about the same. No idea if the calipers will bolt up to the std caliper mounts - you'll have to measure all this up with Verniers, or suck it and see!
Depending on what mix of calipers you end up using, you'll find you have upset the braking balance. You may end up needing to run some sort of adjustable proportioning valve.
