The only part that I can think of that wouldn't work is the center console top. SCs have the e-brake and switches for the fog lights and ride control at the center console.
Other parts may have small differences - the C-pillar panel may or may not have courtesy lights, the instrument cluster bezel may or may not have the automatic headlights and auto-dimming headlights switch and/or a sensor for the climate control, the defroster opening panel may or may not have a sensor for the climate control, the front seats switch panel won't have the same number of switches, the headliner may be different depending on whether the car has a moonroof and whether the moonroof motor is in the front or at the back, the rear seat back may have a center armrest or may fold down, on the LX the panel on the right side of the dash will have the LX badge, etc.
So it all depends on which parts you want to replace, whether you are changing the color of the interior, and how fussy you are.
