I like your idea for the black wood I would love to see it on the car among the rest of the interior. When do you plan on doing it. I just am a little fearful the brushed aluminum might be to light among the light grey interior.
best bet to do any type of drastic change is definitely hydromersion..

take the pieces out, send it to them and get them back looking factory,,prices depend on how much your having dipped so calling them would be the best bet.
Just my 2cents it's kinda of cheap looking and not to sure how quality it will be after year...seems dull finish as well..
