I assumed you meant rotors, calipers, etc. ALL the parts are different front to rear, including wheel bearings, hubs, and mountings for he calipers.
Again, even if you could bolt them all up, and they fit, the system would be dangerous at the least, with the new "rear" brakes locking up at a whim. At best, your ABS would be working full time to release rear caliper pressure as the wheels lock up.
Car makers size brakes front and rear for very good reasons. You'll only find same-size brakes front & rear on full-out race cars, where weight is evenly distributed front to rear, the driver has a control to bias the brake pressures front to back to control the car, and the engineer/builder knows what they're doing with the brakes.
Saabs are usually weight biased about 60% front to 40% rear - standing still. Under braking, weight shifts forward. The less weight over a wheel, the easier it is to lock up to start with. Putting a "bigger" brake on the rear will only exacerbate the situation.
