We do black and white updates from time to time. I wouldn't do just that, but I think it is, like Pseudonymous said, nice for variety.
I'd try promoting your stuff, as we have some model cross-over, but I'm gun-shy on NATS programs these days. If something converts horribly, but I made a few bucks, I made a few bucks. With NATS programs, I'll never see that dough.
