Yes, that Klingon. The Treky one.
I don't have this translation yet, but there are fans of Star Trek who speak this language. Someone even is translating the Iliad into Klingon. No kidding - check out the Klingon Language Institute at: http://www.kli.org/
So it would be possible. It also would be possible with other science fiction languages, like Vulcan. Witness the Vulcan Language Institute at: http://www.vli-online.org/vlif.htm
We suspect that a pole with such a language on it might get increased attention. It is the kind of thing that becomes known, remembered, and pointed out to visitors when a sense of humor is incorporated into a public monument. Imagine how it would keep the monument in the community's consciousness on a school campus.
Just a thought.
I update translations as times change and the way people express things change.
