The Land Shark seems closer to what you might be thinking.I thought of that too- there's a thread about a belly pan on the elio for production models so if you could re-locate the front air scoop higher and if it floats you could mount a small outboard to the rear!
I believe the back wheel also propelled it forward in water.
