lots of money and anything can be done. i'm sure it wouldn't be cheap. i don't see how it would be that hard, the engine is a FR to start out with and all you would need would be a engine with 2wd tranny and just make custom mounts and a custom drive shaft. throw in a nice stand alone engine managment system and yoiur set. not as easy as it sounds but it would be neat. i would stick with the 2rz instead of the 3rz cause of the 3rz's taller deck height cause of its longer stroke meaning it prolly won't fit under the corolla's hood.
