Is it wise to switch 18-55mm and 55-300mm Pentex lens to Sigma 15-200 mm Lens for K-X, thanks.

I have a Pentax K-X with 18-55mm and 55-300mm lens, feel inconvenient to change lens frequently, so want to switch to single 18-200mm Lens, is it wise? How do you think about it?

Any input will be appreciated. Thanks.
