Celica 7th gen rear conversion?

[olidlavoie]

I've looked a bit and I don't think it has ever been done or even discussed, I own a 2000 toyota Echo coupe, and I wonder how possible it would be to cut parts of the rear floor and convert the rear celica suspension on an echo, since it's a much better suspension setup, and it's about the same width (i've got the aero kit anyway so the wheels are already way too far inside the fenders!) so the car could take a complete celica coilover set and become a cornering beast!
