It looks gorgeous! On the Yahoo group of the bfans of the game, people is already exchanging suggestions about where to find suitable miniatures for King Kong...
This looks like a fun variant to try. My memory of the movie is that any plane Kong hit didn't survive. How increasing the number of planes to eight (2 per player perhaps). Use the same rules as written except if Kong hits your plane then you're dead. It'd really start to look like a demolition derby that way.
