Blacked-out grille?

I've always thought the '70 Duster grille was kind of... I don't know... nerdy? Cheesy? I just don't think it looks right on a car like the Duster; it only looks okay on Valiants. So, I was wondering, do you guys think it would be a good idea if I blacked-out the grill myself? Specifically the part around the grille itself that is the matte silver/metallic gray finish. I still have a bunch of leftover multi-purpose spray paint that I used for my air cleaner and wheels.
Would that work okay? And would it be hard to revert it back to the stock finish if I changed my mind? Thanks for your time guys...
