Back when I had my 850R, I was seriously considering doing this, but just on the lower center console to mimic the setup in the V70 R AWD. I began looking on ebay and google and found a few places claiming they did aluminum kits. They'll usually send you a sample and it's normally acrylic coated foil that looks like some sort of silver brushed texture that might look good in pictures, but in person left me wanting more. I opted not to do it.
Chances are, you'll want one actually made of aluminum. I know a guy who has a kit on his VW Golf like that, but it too has some edges that, while not sharp, I wouldn't want to deal with in my daily driver.
When in doubt, go OEM and I haven't seen a kit yet that looks factory clean, at least not in aluminum.
I saw in Terrence's car once, he did an attractive carbon fiber setup. The thing is, even those don't cover the corners exactly right. That's not a bad thing, but you need to remember to paint those exposed areas in a matte black so that any faux-wood trim that your car came from the factory with isn't exposed.
