As I understand your goal, I think you should focus or dungeons that are finished, playable and give a good experience in general. You may want to take a look at
Finished dungeons thread.
There are lots of dungeons around that are half-baked or built around a cool idea, but they don't give end user, i.e. player, not modder, rather poor experience. People may get confused and mistake a review of a specific mod with the whole game and say "that whole Grimrock thing is not finished and have crappy end". We definitely want to avoid such thing.
Anyway, good luck with your plans.
