Yes, tabbers can be customized using CSS.

Help:Tabber is a good place to start. You can use your browser's element inspector to guide with tabber CSS elements.

Also, if you haven't already, install PortableCSSPad, you can preview instant CSS changes before editing .css pages.

I'm happy to try and help out with anything.

Edit: TabberDesign has some interesting tabber designs as well.
