I'm definitely interested. Great idea! As others have said, with a slimmer profile in some sort of aluminum, or faux-aluminum finish that matches the interior trim pieces would be ideal and would help give a hint of premium to that part of the console.
Two other things to consider if you do end up pursuing other interior mods:
1. Some sort of e-brake handle cover. I can imagine a cylindrical casing that basically slides over the first 50% of the brake handle, with an aluminum style look, and open at the front so the black push button is still visible and accessible. That would be a really nice touch. Could be that there is something in dressing that up.
2. The cubby in front of the shifter, as some have mentioned would also be great if it could serve an actual function. It seems like at a minimum being able to hold keys or change would be great, but even better would be the ability for a phone or wallet to stay put in that location.
