l like the paddle shifters, but, l do not like the feel of the 18'' low-profile wheel/tire package that come with the Sport Pkg (the pkg needed to get paddle shifters from the factory).

Can paddle shifters be retrofitted to this car and if so, how hard/expensive would this proposition be?

Retrofitting paddle shifters is an expensive proposition due to physical changes needed to the steering wheel and transmission.

the 2008 models will have that option available on other models besides sport. But it would be expensive to do. the paddles themselves are $200. then the harness and wiring is another $1500. then to install it all will be about another $800. Then about another $500 for anything else l am missing
