BMW Mesh Wheels?

I've been a fan of the Style 312 Wheels that BMW has in gunmetal or silver, does anyone know if they would look good on the 4G TL? Each one weighs 34lbs and is 9x20 ET:44. Would they stick out too much? How do these compare to the factory rims as far as weight? I have the advance 18's on my TL.

Here's a pic with a 535i with them:







Anyone good with photoshop? Would love to see them in silver or in grey on a gray 4G TL.

BTW you can pick these up for around 200-350 each:
