Lens Upgrade Question, Please Advise?

I currently own a Casio EX-Z1000 and absolutely love the quality of pictures that I am able to take, using such a small camera. I would only love to be able to get a little more optical zoom, are/is there currently modification kits, or way of upgrading the lens system to perhaps get a little more zoom? Price is not an issue, simply just wondering if there was a way. Thanks for any help!
