Motorcycle valve stems?

[Alvin]

I know it sounds crazy, but I just got my new wheels and I'm trying to find a valve stem that meets my "vision". The wheels have a light silver painted center and a machined lip. I don't want to run chrome valve stems or caps, but the automotive selection of aluminum valve stems is lacking.

Does anyone know if it's possible to run motorcycle valve stems on automotive wheels?

I found these, and they're freakin' expensive, but would look great (with an aluminum cap of course).
