The space saver can only be fitted to the rear, and since there's no diff on the back, then theoretically one could fit any size wheel as long as it keeps the car above the road. The tyre pressure monitor will think you have a puncture (as it did with my space saver), but it can be reset using the dash button once the 'proper' wheel is re-fitted.
According to tiresize.com your wheel is 26.7 inches diameter, and my space saver was 23.9 inches. IIRC the wheel well diameter is 24 inches.
