Will smaller wheels improve the ride quality of my wife's MINI Cooper S?

My wife runs a 2003 MINI Cooper S which she has had from new. In truth she would have been better served by a Cooper, as the ride quality is not good and potholes must be avoided at all costs. I have noticed that on eBay there are plenty of 15-inch wheels and tyres for sale, as people like to change to bigger wheels. Would it give a noticeable improvement if I bought some of these?

It'll give a softer ride, but I don't know if the wheels will fit around the Cooper S brake callipers. 16-inch wheels will definitely fit.
