The Illustrator graphic styles effect and applied path can be rasterized and then re-used perhaps via live trace - the live trace is now even more amazing with even more features in the latest version CS6.
To rasterize the path / Illustrator graphic style combination, go to the object rasterize command and set the color model as well as the resolution and anti-aliasing option. Select the rasterized artwork and then go to the image trace. The image trace (it seems) is now a lot faster with CS6 / CC. You can also now use the rasterization via the effects menu
Rasterization via effects - new Illustrator graphic style
Go to the effects menu and select rasterize. Set the resolution, background, add space to the art and more. Click OK. The rasterization is a live effect so can be modified at any point. You can also, by click the fill or stroke of the graphic style, add the rasterization to the Illustrator graphic style and that in turn becomes a rasterization graphic style (if saved to the styles panel). You can also modify the rastrization at any point by double clicking on the rasterization line in the Illustrator appearance panel
Above, to do any post rasterization work, you have to expand the Illustrator graphic style - the end result if it contains a rasterization effect of the graphic style is a raster image. Expand via the object menu expand appearance. You can then apply the live trace to the expand design.

Post rasterization of Illustrator graphic styles
The application of the live effects does (if applied to Illustrator symbols) require a little additional work such as going to the appearance panel and selecting the correct fill / stroke to apply the effect to. If applied overall, sometimes you just end up with a solid fill and no evidence of any application of the effect - it is there but just behind or applied to the content / group and the result is probably not the expected one.
Likewise, the live image trace does require some setup as well as some modification of the end result / threshold (especially) as sometimes the result is either a silhouette or a white screen.
