That's basically how I went from Marketing Associate to Associate, at one time. Of course, when there are 5 employees in the whole organization, job titles don't mean a lot. My current card doesn't even have my last name, let alone a job title. I realize that wouldn't work for some people, but I'm self-employed / a freelancer, so as long as I'm making a living, I don't care about convention. And, the no-last-name thing, that's because 9 times out of 10, when I say my last name people say "what?" Not "can you say that again" or "pardon" or anything remotely resembling politeness: they say "what?".
