Hmmm....how about an Ultralight with ballast tanks, electric motors, 
batteries, depth and other necessary gauges and a few other odds and ends to 
make it work as a wetsub? From what I've seen of ultralights they are very, 
very simple and wouldn't need that much to become a wetsub with limited range 
and speed, but it sounds doable to me.
