I would say changing the look is fine as long as you make it simpler and cleaner rather than more complex and cluttered. I think it would be possible, with skilled design, to make the site look more modern, easier to read and more professional by making it simpler and messing around a bit with typography and CSS.
Don't change it radically, we like it for a reason -- it's simple and clean. Changes should be designed to make it more so.
