Has potential, but the Sky Cannon sucks, and the Drill Cannon is worse than the ones that Endrinriggers have, so I would probably take some endrinriggers as they are just as mobile if not more so.
I once saw a KO conversion however they made it so that the balloon wasn't metal and the hull was made of wood. With some smokestacks and steel textures, it could definitely break up the whole KO look and make it look straight from a factory. Just a suggestion though, and a good idea that I might keep around😉.
Hey, you should take a look at some KO bits. A steampunk blimp would look super cool. In any case, this is by far the most detailed and well-done completely custom conversion army I have ever seen! Actually, its the best army I have ever seen period.
Srsly though, a blimp would make the whole army seem less grounded if that makes sense. Sort of a gyro bomber on steroids, like what zeppelins did in real warfare.
