Hey, it'd be like having two vehicles with different customization styles for the price of one. I've considered the same thing in the past, but being as picky as I am about the wheels I put on my vehicles, I've rarely been able to find two styles that I like equally well at the same time.
In the end, it's your vehicle though, so if it's something you want to try, I say why not? It's not like you'd have to leave it that way if you ended up not liking it as much as you'd thought you would.
(On a more local note: You going to Frog Follies this weekend?)
