Can packing be used to enhance flavor

[srains99]

This may be a foolish question but I was reading a post concerning different packing materials (lava rocks) may improve distilling but I was wondering if packing material could be used to enhance the flavors of the product. I have copper scrubbers but what if I unrolled some and filled them with charred oak, walnut shells, rock candy or something else that would allow the scrubbing (perhaps a little less effective) to take place while at the same time adding flavor. Of course air still has to be able to pass through the scrubbers.

Just wondering thanks
