I don't have any currently in development, but it should be pretty easy to brew up. I'll add it to the queue.
If you're looking for something in the meantime, there's a few other water-y Mork Borg supplements that I know of, although I haven't read them yet. Corpsewalk Cove, Bridges Of Mur, Glasro Island, The Horde From Beyond, and Temple Of The Kraken God, and there's probably a bunch more out there.
