Heh, I'm afraid I'm more like you: Lots of concepts, ideas and dreams and no time to make them come true. When it comes to LucasArts, you should not forget that many of the Lucasfilm Games veterans don't work for that company any more (pretty much since Jim Ward became president of LucasArts). Nowadays LucasArts seems to be nothing more than a StarWars (and perhaps Indy) license administration for the computer game market. Other than that, they're busy shutting down fan-projects like LucasFan Games.

I can't remember any recent project they did in-house (well, except those promising adventure projects that got cancelled in development). Alas, I still wish you good luck with your endevours. Just don't count on LucasArts showing any kind of enthusiasm for your enthusiasm. This might change if you deliver a completely developed product that's ready to be marketed. Hasn't happened in the past though.
