Alien, while I get the idea you're going for, I don't think that's a particularly helpful attitude.
Why? Carrie Fisher might have just been an actress (she wasn't, though, she was a thoroughly talented writer and script doctor) an actor can have just as much influence on a genre through their performance as a writer or a director. Film is an amalgamation of talent, and George Lucas is not solely responsible for it being what it is. Fisher is not just a puppet on a string. Actors bring more to a role than a mouth to say words with.
But regardless of talent, consider the idea of what her most iconic role represents. Since you're posting from Facebook, I'll do the same:

Carrie Fisher as Princess Leia was one of the more influential characters on me growing up. Along with children stories like The Paper Bag Princess or, heck, even Miss Piggy, they kept coming back to mind whenever I saw generic damsels in distress on movies and TV. It didn't take me long to realize who was more interesting and memorable, and who I'd rather write about in my own stories.

Anyway, my point is there is nothing wrong with honoring an actor/actress that had a significant impact on how we view science fiction (or the world), any more than a writer or a director.
But I will agree with you in that we shouldn't be making station naming some kind of "go-to" tribute. This goes on much longer and they will never NOT be able to, because butt hurt fans will say "well, why is my favorite XYZ less important than THAT XYZ that got their own station? Or worse: "Mine should get a full station, not just an outpost." (or a planet, or a star, etc etc...)
In short, we do need to find other ways to show respect to people. CGs, NPC names (they can always use more variety), GalNet articles with an in-joke reference, etc...
